The long range 169 Mhz standard toolkit consists of a set of transmitters plus a receiver.
temperature and humidity sensors
- 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
|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.
