temperature and humidity sensors
The temperature and humidity Enless sensors - TX TEMP HUM AMB 700-022 - embed a SHT21 manufactured by Sensirion
- L2 and L3 (on the transmitter) remain lit for 1 minute if radio quality is good
- L1, L2 and L3 (on the transmitter) remain lit for 1 minute if radio communication quality is poor.
- With a repeater, you can have L2 and L3 blinking on the transmitter, even though the data packet is correctly repeated
temperature, humidity and CO2 Sensors
2 modes : calibration and communication
When powered, the sensor can be either in calibration or communication mode
| mode | sequence |
|---|---|
| calibration | L1,L2,L3 blinks successively then remain all lit for one minute |
| communication | L1,L2,L3 blink successively L1 blink each 2 second L3 remain lit if radio quality is good |
If you are in calibration mode and want to enter communication mode (or vice versa), just power off the sensor for one-minute and power on.
