HiLetgo Temperature Probes & Sensors Editorial Review
The HiLetgo 2pcs DHT22/AM2302 Digital Temperature And Humidity Sensor Module is a high-quality product with better accuracy and wider ranges than the DHT11. It works well with a variety of devices such as the Raspberry Pi and Arduino without any issues if connected to 3.3V. The package includes two pieces of the module that are easy to install and well labeled. The sensor provides accurate readings for temperature and humidity, making it desirable for IoT class projects such as remotely monitoring conditions. However, some customers have experienced difficulty with mounting the sensor, which can be easily detached from the PCB, and getting it to work in conjunction with a Raspberry Pi without overheating. Adding a resistor between the data and 3.3V connection improves the readings, and while the PCB layout could be a little neater, the product itself is of good quality.
