UV lamp work protection, to prevent the UV lamp from being turned on when there are people around and causing personal injury It has good environmental adaptability, and the sensing effect is not affected by the surrounding environment such as temperature, brightness, humidity and light fluctuations； Wed Sep 07 01:06:00 GMT+08:00 2022: Characteristic 0000fff1-0000-1000-8000-00805f9b34fb changed | value: F4 F3 F2 F1 0D 00 02 AA 03 4C 00 55 00 00 64 00 00 55 00 F8 Wed Sep 07 01:06:00 GMT+08:00 2022: Characteristic 0000fff1-0000-1000-8000-00805f9b34fb changed | value: F4 F3 F2 F1 0D 00 02 AA 03 49 00 3C 00 00 64 00 00 55 00 F8 The LD2410 has a number of 'gates', each of which correspond to a distance of about 0.75m and many of the settings/measurements are calculated from this.
Accurate identification within the interval, support the division of the sensing range, and shield the interference outside the interval Wed Sep 07 01:06:00 GMT+08:00 2022: Wrote to descriptor 00002902-0000-1000-8000-00805f9b34fb | value: 00 00 Once you have your hardware ready, the next step is to flash the required software to your device. The flashing process involves installing ESPHome, a powerful tool that allows us to integrate custom firmware with Home Assistant seamlessly. Here's a step-by-step guide to the flashing process:This is a mmWave prescense sensor based on the LD2410B sensor, primarily for use in Home Assistant. Using a well-designed 3D printed shell (designed by CSZ), it can be easily pasted on the wall, and the side with the Logo is facing the direction you want to sense. From then on, your HA can flexibly sense people coming and going up.
The code in this library is based heavily off this piece of work for ESPHome and the manufacturer datasheet. Define the desired actions for each trigger state. For example, you can turn on a specific light when occupancy is detected and turn it off when the area becomes unoccupied. This product is mainly used in indoor scenes to sense whether there is a moving or micro-moving human body in the area, and output the detection results in real time. The farthest sensing distance can reach 5 meters, and the distance resolution is 0.75m. Provides a visual configuration tool, which can easily configure the sensing distance range, sensing sensitivity in different intervals and unmanned delay time, etc., to adapt to different specific application needs.

The defaults do a good job of spotting an adult person and estimating distance.

Both moving and stationary targets are detected separately, with a value for each in centimetres. The accuracy of this distance isn't amazing but given this sensor is targeted as a replacement for something like a passive infrared sensor it's a very big improvement.
The LD2410, as sold for configuration with the common breakout boards shown above communicates over serial at 256000 baud by default. This library allows you to configure and use the sensor over this serial connection. As the LD2410 is a device that uses a high baud rate, a microcontroller with a spare hardware UART for this communication is preferable to bit-banged software serial. LD2410-P(with BLE)" is what is elsewhere referred to as an LD2410B, I think. This one can operate with just 5V power and can both be calibrated and monitored over BLE, although some folks have said the range and connectivity is a bit spotty. Since I mean to house it with an ESP32, using the BLE connection seems pointless, but this module (the same price as the above) might still be a better choice, if only to ignore the BLE (can I do that? Does it work OK without?) and hardwire the connections without having to desolder the header pins, since this one comes without a header. Introducing Hailingco Electronics' LD2410 mmWave Human Presence Sensors - the perfect addition to your smart home network. With Bluetooth support and compatibility with Home Assistant (they were added to Home Assistant in version 2023.02), these sensors fill the gap left by traditional PIR motion detectors that forget you're in the room if you're not moving!

Reading distances
Fortunately, the latest kernel of arduino solves this problem, but there is still a little problem with the uart library from esphome. An Arduino library for the Hi-Link LD2410 24Ghz FMCW radar sensor. This sensor is a Frequency Modulated Continuous Wave radar, which makes it good for presence detection and its sensitivity at different ranges to both static and moving targets can be configured.Tap on the "Connect" or "Start" button within the HLKRadarTool app to initiate communication with the LD2410B sensor. The modules also provide an 'active high' output on the 'OUT' pin which can be used to signal presence, based off the settings configured. Once the modules are configured it is not necessary to use their UART, but it provides much more information.
