Homekit All-in-one Sensor

1. Product Introduction:
All-in-one sensor for Homekit based on ESP-12F
 
2. Application Scenario:
It can be used for temperature, humidity, light and human presence detection in the home
 
3. Product Overview:
Collect data from radar sensors, temperature, humidity and light sensors, report to Homekit, or view on the mobile phone
 
4. Product Parameters:
1. Hardware parameters:
Using ESP8266 (ESP-12F module) as the main control
Human presence radar uses LD1115H, and LD2410 can also be used
Temperature and humidity sensor uses high-precision SHTC3, humidity measurement range: 0~100%, accuracy ±2%; temperature measurement range: -40~+125℃ (-40~+275℉), accuracy ±0.2℃
Light sensor uses BH1750, measurement range 1-65535lx
 
2. Electrical parameters:
Working voltage: 5V DC
Working current: about 500mA
External interface: ESP download interface
 
3. Specifications:
Size: 38mm * 38mm Double-layer board can be double-sided patch
5. Instructions for use:
Power on the sensor -> Connect the sensor Wifi network -> Add the sensor in the "Home" App
Long press the back button of the module to force delete the pairing information, and you can rebind Homekit
 
6. Remarks:
This project needs to be run with the software, please refer to the attachment for the source code.
The human presence sensor is divided into LD1115H and LD2410, and the schematics have been uploaded.
Pay attention to the temperature when welding BH1750 to avoid burning the sensor.
The shell file can be printed directly
