Little Bird presents the DHT11 digital temperature and humidity sensor. It's a combined temperature and humidity sensor in one, made in Sydney, Australia. This sensor is pre - calibrated, so you don't need extra components and can start measuring relative humidity and temperature right away. It features low power consumption, long - term stability, and a calibrated digital signal. With an integrated high - performance 8 - bit micro - controller and calibration coefficients saved in OTP memory, it offers accurate temperature readings. It can operate at 3.3V, making it compatible with Raspberry Pi, Intel Edison, Joule, Curie, Micro:bit, and Arduino. The package includes 1x DHT11 Module and 1x wire with a header. Specifications are 3.3 - 6V input, 1 - 1.5mA measuring current, 40 - 50uA standby current, humidity range from 0 - 100% RH, temperature range from - 40 to 80 degrees C, ±2% RH accuracy, and ±0.5 degrees C. Note that the yellow cable is GND.
Using this DHT11 temperature and humidity sensor is easy. First, check the power supply. It can work with a 3.3 - 6V input. Make sure to connect the wires correctly, and remember that the yellow cable is the ground (GND). Once it's connected, you can start getting readings of temperature and humidity right away. Since it's pre - calibrated, you don't have to worry about adding extra components. For the best results, keep it in an environment within its specified temperature and humidity range (- 40 to 80 degrees C and 0 - 100% RH). When it comes to maintenance, keep it clean and dry. Avoid exposing it to extreme conditions. If you need to use it with devices like Raspberry Pi or Arduino, you can find the relevant code easily. Just have fun using it to measure the environment around you!
