Crowtail – Temperature and Humidity Sensor 2.0

This module can help you detect the temperature and humidity of the environment of your house. The module contains a DHT11 Temperature and Humidity sensor that is a complex sensor with a calibrated digital signal out. It uses digital module acquisition technology and the temperature & humidity sensor technology. The sensor consists of a resistance-type moisture element and an NTC temperature measuring element. Because of the single-wire serial interface, it is easy to use the module.

• -Work Voltage: 3.3 Volt ~ 5 Volt
• -Measuring Range: Humidity: 20% – 90% RH
• -Measuring Range: Temperature: 0 ~ 50 °C
• -Signal Collecting Period: 2S
• -Accuracy: Humidity: ±5% RH
• -Accuracy: Temperature: ±2°C
