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.
Size: 193.5mm x 29.4mm

SONOFF® TH16 DIY 16A 3500W WIFI Temperature Humidity Thermostat Module APP Switch Socket + sensor unit (Sonoff TH16 dual + sensor)
Overview - Control Unit

Sonoff TH10/16 is a Sonoff version that can monitor and set temperature and humidity through the APP eWeLink. Just as the name indicated, the new version Sonoff TH device supports two power supply specifications- 10A or 16A. It supports preset a temperature and humidity range, when the temperature and humidity of the environment falls into the range, it will automatically turn on or turn off connected devices.

The device supports connecting to three kinds of temperature and humidity sensors (AM2301, DS18B20, DHT11). Actually, Sonoff TH 10A/16A Sonoff TH 10A/16A can work as a Sonoff when without connecting to sensors. But compared to Sonoff, Sonoff 10/16 is more safer, less radiation and in bigger size, easy operation. Most importantly, with the support of latest ewelink app, you can create chains of simple conditional statements(Smart Scene). This means you can use the them with temperature and humidity sensors (AM2301, DS18B20, DHT11) to collect data, while these data can be shared to other ITEAD smart home devices(Sonoff, Sonoff RF, Sonoff SV, Slampher, smart socket, etc.) under your account, thus other devices can use the data to control connected appliances. This device is perfect to work with electric fan, air conditioner, humidifier. Please note that this version does not have 433 RF function.

Features:

- Supports 90~ 250V AC input
