ZIGBEE Garden Soil Moisture & Temperature Meter,Sensor-Outdoor Waterproof,Plant Humidity Tester,Compatible with TUYA Smart APP

Product Information

After a few years, of course, they changed their name to Spruce and now works not only with Smartthings but it’s own app as well. Support is amazing, and you’ll probably get a response from the founder. I think it’s still a relatively small company. Unfortunately, I could not disassemble the device further without completely ruining the IP67 rating, which is crucial for this device. It meant prying it open by force, which would have broken the seals on the top and bottom caps and render the product unprotected against moisture. Everything was sealed shut with glue, so there was no getting in without breaking it completely. Your power source is OK (a battery has more than 3V). You can temporarily use an external power source for testings (for example, from a debugger). Once integrated, the sensor worked as I expected in Home Assistant. Readings were reactive to me pouring water inside the flower pot and reported after a while in HA. Here are some charts graphed with the History Explorer Card: HHCCJCY10 Temperature HHCCJCY10 Moisture HHCCJCY10 Illuminance HHCCJCY10 Conductivity Summary

Connect the moisture sensor/diode/CC2530 and turn on the power. Make sure HA allows new devices to join. Use the MQTT explorer ( http://mqtt-explorer.com/ ) and connect to HA and look for the newly added device. You should see something like: zigbee2mqtt/0x00124b0009e004d5 Sonoff also has a soil sensor Soil sensor for the the TH10 and TH16, benefit is it’s not battery. Only thing is I have a TH10 with a temp sensor and when it was unplugged the value in HA stayed the last value for days. So if the sensor fails for some reason I won’t know until I see dead plants. I also have a Tuya temp sensor just like the Sonoff TH10 and that one showed the sensor was off line when I unplugged it. In general, the sensor turned out to be very sensitive, when the window is open if it is raining outside, the sensor feels like dry ground absorbs moisture. The graph shows that you need to select a resistor in the light sensor circuit. In the Home Assistant community forum stanvn mention plans to create new modified hardware for it with more or other features: I am looking into getting some soil moisture sensors for irrigation control (rainmachine) and a few separate areas with smaller potted plants via a Wi-Fi water valve on the hose faucet.All sensors except the sonoff need battery power have, I would likely try to convert them to usb power if I can. They measure soil moisture, temperature, conductivity and also have an illuminance sensor pushing values in LUX. I recently reviewed an interesting Zigbee-based Soil Moisture sensor white labelled Tuya GXM-01. That one turned out to be a hit and miss, because different users reported different experience with the device. It’s also much much larger than the MiFlora Plant Sensors, which are more suitable for small, in-house plants. As far as I know, Spruce Spoil Moisture Sensors by Plaid Systems is currently the only existing commercial Zigbee-based product that you can already buy which matches most of the description, except that is relatively expensive and large (plus it has an ugly colour and design that does not fit indoor flowers IMHO, though in its defence its size and price are probably due to it being fully waterproof as primarily design to outdoor use in your vegetable garden rather than potted plants indoors). I’ve been playing with a few sensors recently. One thing to keep an eye on in the capacitive vs resistive type of sensors. Some have reported the resistive type corroding and causing issue in their automated setup. We are currently developing more products related to smart gardening, and I would greatly appreciate your valuable input and suggestions.

Does anyone know of relatively low-cost Zigbee devices that meet all or most of those requirements? Recently, WSNs have contributed to achieving advances in real-time hydrological monitoring [ 92]. For instance, WSNs have been used to develop real-time flood monitoring systems that combine soil moisture sensors with hydrometeorological sensors to provide important information for the efficient management of flood events [ 93, 94]. For example, a ZigBee-based WSN was used for an early flood monitoring and warning system to provide flood warning. The WSN system informs the public of the water level even without network connection in their mobile application and helps them to reach a safe place in a timely manner [ 95]. Furthermore, real-time soil moisture WSNs have been used to develop local early warning systems for drought that combine soil moisture data from a WSN with hydrologic model data and locally observed precipitation [ 96]. I was unable to completely pry open the device without ruining it’s water resistance IP67 rating. It was completely glued shut and wouldn’t budge. Using more force meant I will potentially break the case caps and render it vulnerable to moisture or rain if installed outside. Recent advances in sensor techniques allow for continuous non-invasive soil moisture measurements that integrate over scales beyond the traditional point measurement [ 27]. For instance, cosmic-ray neutron sensors (CRNS) provide non-invasive soil moisture estimates at the field scale with an effective radius of 130 to 240 m and a penetration depth of up to 80 cm [ 95]. Recently, data from a network of CRNS stations in Europe has been published [ 121], but a large proportion of the stations are not equipped with data transmission. Equipping all CRNS stations with WSN technology would allow the soil moisture data to be available in near real time, e.g., for use in improving flood models within the European Flood Awareness System [ 122]. WSNs have already been successfully deployed in various locations around the world, providing a large number of soil moisture measurements (see references in Table 2). For instance, the SoilNet WSN installed in a headwater catchment has continuously operated since 2009 and has already produced more than 50 million soil moisture measurements [ 80]. Most WSN studies of soil moisture were focused on the investigation of hydrological processes at the field and catchment scale [ 14, 16, 66, 80]. For instance, Bogena et al. [ 14] analyzed data from a SoilNet WSN implemented in a headwater catchment and found that soil moisture variability in forested mountainous regions can be remarkably high during intermediate wetness conditions. Similar results were found by other studies in mountainous regions using campaign-style soil moisture measurements with handheld sensors [ 31, 89]. However, the SoilNet data showed less scatter than such discontinuous soil moisture measurements, indicating that WSN data provide more detailed insights into the hydrological processes generating soil moisture patterns [ 66, 90, 91]. Bogena et al. [ 14] also showed that soil moisture variability strongly decreased with depth, indicating that the factors controlling prolonged travel time decrease the spatial variability of soil moisture. In addition, topographic attributes had the strongest correlation with soil moisture during dry conditions, suggesting that the control of topography on soil moisture patterns depends on water storage in the soil. Finally, it could be shown that interpolation of the densely sampled point data from SoilNet allowed the capture of the key patterns of soil moisture variation at the catchment scale [ 14].

Compliance, Ethics & Privacy

This is a compact wireless soil moisture sensor, supports working in Zigbee networks. (Zigbee2mqtt open source project, ZHA open source project). The device has an industrial look, at least, I wanted to achieve this. The sensor has very good energy efficiency. Powered by CC2530 chip (Zigbee). The device comes with pre-installed open source software.

In the past decade, soil moisture WSNs contributed to several validation activities of satellite missions such as the SMAP (Soil Moisture Active and Passive) or SENTINEL missions by providing reference data [ 18, 98]. In addition, soil moisture data from WSNs were used for the calibration and validation of simultaneous passive/active microwave airborne campaigns in the Rur catchment [ 99, 100] to analyze various radiometer–radar fusion methods for retrieving improved soil moisture data products [ 101] and to develop methods for downscaling SMAP radiometer data [ 17]. LilyGO TTGO HiGrow is ESP32 WiFi-based but otherwise almost perfectly matches that description however I would instead like to use Zigbee and some type of standard battery that is widely available. As you can see, the boards in the photos are slightly different from the design image. The fact is that this is the first version of the boards, the second was supplemented with the ability to use a ready-made BME280 module since not everyone can cope with sealing the "bare" chip. In addition, a more convenient connector for CC2530 I do not measure soil moisture, but the speed at which the flower leafs go down. I use laser ranger once an 4 hours and I set up derivative sensor to calculate movement per hour and if it is more than 5mm/hr it sends me Telegram notification. The leafs are BIG, so for smaller flower speed should be less. It works for about three months on battery charge. I also measure battery.
