We use a V2 vibration and temperature sensor with frequency analysis (https://store.ncd.io/product/industrial-iot-wireless-vibration-temperature-sensor/) to measure the vibration of a fan.
For the first 3 months, we took 1 reading every 15 minutes. Then, last Friday, we increased to 1 reading per minute. The sensor batteries then drained very quickly. The voltage went from 3V to 1.9V in 2 days, then the sensor stopped emitting (see the purple curve).
The main settings of the sensor related to the power consumption are :
1- Power: 4
2- Filtering : yes
3- Delay : 60 s
Do you believe that the emission power can have a significant impact on the life of the batteries that could explain this poor performance? In the case of this plant, the sensors are close to the receiver (maximum 100 feet).
Thanks in advance for your feedback
