Although there are already too many temperature and humidity sensors out there, that's almost the most common sensor out there, we're still happy to have one of these sensors for the following reasons:
- The use of the TLSR8253 processor, the years-long research on these chips by pvvx and others, the complete conversion of many commercial sensors to homemade, open-source firmware, optimised for power savings, etc., and the fact that these firmwares are excellent for learning these protocols as well as being a good place to start.
- Open source firmwares, no cluttered broadcast packages, no extras, they are very pure.
- Larger coin cell batteries, as Zigbee typically requires more broadcast data than the latest BLE protocols, the power consumption increases accordingly, larger batteries help to keep the batteries running for more than a year while retaining a very high refresh rate. The default is roughly once every 30 seconds. measured once every 10 seconds.
- With reset button, long press can reset the Zigbee data, when you are not satisfied with it in a certain Zigbee gateway, use not to delete the Z2M configuration information at the same time to reset the device, you can let it to join the specified sensors (by turning on the join permission of the corresponding gateway device)
- The back has a magnet adsorption function, which can be adsorbed to metal objects.
- Comes with two bracket attachments, wall mount to and desktop placement.
- Ability to measure temperatures up to -9 degrees.
