DHT12 Digital Temperature&Humidity Sensor Module Compatible DHT11 for Arduino

Product Overview
DHT12 temperature and humidity module is compatible with the Arduino sensor shield. It is a temperature and humidity composite sensor with a calibrated digital signal output, an upgrade to the DHT11.
It uses dedicated digital acquisition technology and semiconductor temperature and humidity sensors, to ensure high reliability and excellent long-term stability.
The DHT12 has a single bus and standard I2C communications, and the single bus communication is fully compatible with DHT11.
You can select the communication mode by setting the DIP switch on the module. If select the single bus communication mode, the communication interface is SDA.
The module comes with 4 positioning holes for you to secure the module onto other devices.
