TZT DHT22 Temperature and humidity sensor

The DHT22 sensor, connected to a module such as the Smart Implant, allows you to transmit the temperature and humidity of an area (for example, a room in your home) to a home automation controller.

Therefore, you can use this information in automation that can autonomously activate, deactivate or vary a VMC, heating or air conditioning.

FUNCTIONS:

Measure temperature
Measure humidity
TECHNICAL CHARACTERISTICS :

Voltage: 5V
Measurable temperature range: -40 to + 80 ° C (accuracy: 0.5 ° C)
Measurable humidity range: 20-90% RH (accuracy: +/- 2% RH)
Dimensions (width x width x height): 3.7 x 2.1 x 1 cm

This sensor is the wired version and encapsulated in a plastic body of the well-known DHT22, very easy to use with Arduino and Raspberry Pi.

It is a very simple to use and very accurate sensor, its only drawback is that the readings are every 2 seconds. The red wire connects to power (3-5V), the yellow wire to the data pin, and the black wire to ground (GND).

Compared to the DHT11 this sensor is more accurate and works in a wider range of temperatures and humidity.
