DHT12 Digital Temperature and Humidity Sensor Module Compatible DHT11 KEYES for Arduino - products that work with offici

Features:The Keyes DHT12 temperature and humidity module is anspecial sensor. Its connection port is compatible with thesensor expansion board. It is a temperature and humidity composite sensor with calibrated digital signal output, which is an upgrade product of DHT11. It uses dedicated digital module acquisition technology and semiconductor temperature and humidity sensors to ensure high reliability and excellent long-term stability of the product. DHT12 has two kinds of communication, one-bus and standard I2C, and the one-bus communication mode is fully compatible with DHT11. By setting up the dial switch on the module, we choose the communication mode. When choosing the single bus communication mode, the communication interface is SDA. The module has four positioning holes, which make it easy for you to fix the module on other devices.Specification:Working Voltage: 3.3V-5V (DC)Interface: 4PIN InterfaceCommunication: Single Bus and I2CTemperature range: - 20 ~60 ~0.5 ~Humidity range: 20-95% RH + 5% RHResolution: 0.1 C 0.1% RHPackage Included:1 x KEYES DHT12 Digital Temperature and Humidity Sensor Module
