the DHT component is a common electronics component you can incorporate into your digital electronics projects to obtain the ambient temperature of the environment it operates within.Works great with the raspberry pi and arduino.Easy to (physically) install in the breadboard. Easy enough to interface with in software.

we got this to track temps in our freezer to let us know if it ever starts to get warmer aka the freezer goes out. So far it has been accurate and seems to be doing well. It was pretty easy to set up. good investment for peace of mind without costing too much.

I'll keep buying DHT11 for 2.50 instead of these for 11.00. The actual humidity is 36%. The DHT11 calls it 42. The DHT22 calls it 45! Huh? 8.00 more and it it 1% farther off.

DHT sensors contain a capacitive humidity sensor, and a thermistor, the embedded circuitry provides conversion from analog measurements to a digital discrete output.This sensor type, for Temperature and Humidly general com in two flavors: DHT11 and DHT22 (this product), the DHT11 is the lower cost brother to DHT22 and provides a much lower accuracy and usable range.I replaced my Arduino DHT11 sensors with DHT22, including this product. Most of my sensors are located outdoors in an area with wide temperature ranges. The DHT11 sensor will only measure temperature to a low value of 0 degrees Celsius which we frequently surpass on the low end. The DHT22 sensor (this product is rated down to -20 degrees Celsius. In addition to range, the temperature accuracy of the DHT22 is +/- .1 degree, the DHT11 is a whopping 1 degree.*I tested this particular product using a calibrated digital freezer thermometer on the low end, and a calibrated thermocouple on the high end. The Cold measurement was within .08 degree, and the high end was within .11 degree. Excellent readings for such a low priced deviceArduino Users: Ditch your old DHT11 sensors and replace with this DHT22. The price difference is small for the tradeoff in accuracy and useable range.

I recently purchased the DHT22 from SHILLEHTEK for my Raspberry Pi and Arduino projects, and I'm genuinely impressed. The sensor's compatibility is seamless, and it works flawlessly, providing accurate readings consistently.
