Frequently Asked Questions
What supply voltage does the DHT22 require?
The DHT22 operates on any supply between 3.3 V and 6 V DC. It is fully compatible with 5 V logic rails commonly found on Arduino boards and similar controllers.
Is an external pull-up resistor needed?
Yes. A 4.7 kΩ to 10 kΩ pull-up resistor between the DATA line and VCC ensures reliable single-wire communication and clean digital pulses.
How often does the DHT22 update its readings?
The sensor refreshes its temperature and humidity measurements every two seconds. Attempting to read at a faster rate may result in stale data or communication errors.
