Wemos® Higrow ESP32 WiFi + bluetooth Battery + DHT11 Soil Temperature And Humidity Sensor Module (Wemos Higrow)
Description:
 
More details available at:https://github.com/LilyGO/higrowopen


A LG 3000mAH 18650 battery could make ESP32 run 17 hours or more.
This capacitive soil moisture sensor differs from most of the resistive sensors on the market, using capacitive sensing principle to detect soil moisture. It avoids the problem that the resistance sensor is easy to corrode and greatly prolongs its working life.

SONOFF SNZB-02 ZigBee Temperature And Humidity Sensor Real Time Low-battery notification Works with SONOFF ZigBee Bridge eWeLink APP (zigbee SNZB-02)

Note 1: Batteries not included - ( 3V CR2450)
Note 2: SNZB-02 must be used with the Zigbee Bridge.

SONOFF SNZB-02 is a ZigBee temperature and humidity sensor that can seamlessly work with SONOFF ZigBee Bridge to track and record the temperature and humidity change in your home, which all real-time readings can be checked on eWeLink APP. Better still, you can set a condition in the smart scene that is the fan is turn on/off when the temperature reaches the limit value, or the dehumidifier in your room starts working once the humidity is over higher, helping prevent the growth of mildew and allergens. You can set a smart scene to trigger alerts through events like high/low temperature, high/low humidity conditions and more.

Device sharing function makes your kids, family, and even the neighbors informed about the environmental conditions of your home with their mobile phones.

It is a battery-operated sensor that can be placed in any corner of your house to monitor the room temperature and humidity. Installation without any tool, simply stick the sensor on the surface of the wall or device and see it nicely to work for you!

1. Do not install on a metal surface, it will affect the wireless communication distance.
2. Installation height of less than 2 m is recommended.
3. The device can be operated intelligently via working with the SONOFF ZigBee Bridge to communicate with other devices.
