## Customer Reviews

### ⭐⭐⭐⭐⭐ Good value, works well
*by S***E on 18 March 2025*

Have used these as part of my underfloor heating controls. Have placed one in each room and wired back to Raspberry pi 4 which controls the relay on each UFH circuit

### ⭐⭐⭐⭐⭐ Reliable sensor, easy setup, online manual, clear pinout, and works well.
*by A***R on 22 January 2025*

🌡️ The AZ-Delivery DHT11 temperature and humidity sensor works reasonably well and includes a calibrated digital output with a reliable 8-bit microcontroller. It operates between 3.3V and 5.5V with a simple one-wire interface. Like all similar sensors, it benefits from software calibration if your controller ecosystem allows, as slight differences can occur even between identical boards, which is to be expected. The sensor element is not fixed to the PCB, so I added a spot of glue for better mechanical robustness. The pinout is clearly printed on the PCB, though mirrored underneath, which isn’t an issue as the orientation aligns with the legend.🌡️ I found the sensor very easy to connect and use, and the manual is a useful addition, providing detailed instructions and examples. I like that the manual is available online before purchase, allowing evaluation beforehand. These resources make setup straightforward and save time during configuration. ✔️

### ⭐⭐⭐⭐⭐ all good
*by B***E on 9 December 2024*

I am very pleased another purchase. Thermometers are precise, not tested for humidity reading
