Microcontrollers on boards using the DHT22
What boards using the DHT22 are built for
DHT22: common questions
Where can I find a DHT22 reference design?
Each of the 4 boards on this page is a real design using the DHT22. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
Which microcontrollers do boards using the DHT22 use?
Most are built on Raspberry Pi (2) and ESP32 (1).
How big is a typical board using the DHT22?
The median is 107.2 × 86.1 mm, and 75% are two-layer designs.
What is the most popular open source board using the DHT22?
By GitHub stars, ClimateSprinklerController by kbx81, with 54 stars.
Can I simulate one of these boards using the DHT22 before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
