What

It's a sensor that measures total volatile organic compounds (TVOC).

Hardware

See https://nl.aliexpress.com/item/1005006125242045.html

Sensor consists of a wemos d1 mini and an ENS160/AHT21 module. The AHT21 is used to compensate the readings of the ENS160.

Connections:

• Vin = wemos 5V
• GND = wemos GND
• SDA = wemos D2
• SCL = wemos D1

Software

It is programmed with ESP-home:
