Arduino Library – DHT sensors (ESP8266)
Installatie van Arduino IDE libraries: Arduino info
Dit is een DHT11/22 bibliotheek voor de ESP te gebruiken met ArduinoIDE, de DHT sensoren hebben een zeer nauwkeurige timing, daarvoor is deze bibliotheek speciaal gemaakt voor de ESP platform.
Informatie (ENG)
Interrupt driven DHT 11/21/22 sensor library for esp8266
If you get too many checksum or timing out err, set cpu frequency to 160MHz
tests:
160MHz/5sec report: 13.13H, 9400, err : 20(large sketch, too many err with 80MHz)
80MHz/5sec report: 8.1H, 5816, err : 0(simple sketch)
Interrupt driven DHT 11/21/22 sensor library for Spark
Supports reading DHT22/DHT21/DHT11 sensors without disabling interrupts
