Pin Diagram DHT22 is available as a 4-pin single rowed package. This sensor module calculates temperature values in Celsius. These values are then converted into Fahrenheit and kelvin using conversion formulas. The pin configuration of this sensor is given below Pin-1- VDD- is the power supply...
Once I plug it into an Arduino, with the same pin configuration, it works.I'm connecting the sensor's Vcc -> 5V / GND -> GND / OUT -> GPIO4 With a 1K pull up resistor.The current driver is as follows: Code: Untitled.c Select all /* * Copyright (c) 2016 Jonathan Hartsuiker...
