Arduino DHT11 humidity and temperature sensor

Arduino DHT11 humidity and temperature sensor

Description:

Sensor DHT11 is use for highly precious temperature and humidity measuring. Data transfer ongoing on one line (conductor) based on own protocol. Sensor DHT11 could be use in devices with microcomputer Arduino, AVR, PIC, ARM etc. Sensor is in socket appropriate for outdoor use. Typically, applications are meteorological stations, systems for autonomous heating and systems for irrigating control.
