DHT11 Temperature & Humidity Sensor features a temperature & humidity sensor
complex with a calibrated digital signal output. By using the exclusive digital-signal-acquisition
technique and temperature & humidity sensing technology, it ensures high reliability and
excellent long-term stability. This sensor includes a resistive-type humidity measurement
component and an NTC temperature measurement component, and connects to a high performance 8-bit microcontroller, offering excellent quality, fast response, anti-interference
ability and cost-effectiveness
Although The DHT11 module has interface compatible with ESP-01 family, it can also be used with ESP8286 NodeMCU families
Due to the proximity of components and how they are positioned in relation to the DHT11 module, you may see variations in the measures. Consider to keep your device in sleep mode while not using to minimize the variations.
