Battery life on a cellular logger is not a number on a datasheet, it is the result of two settings: how often it measures and how often it transmits. Genesis lets you set both from the dashboard after it is installed, and sleeps under 30 µA in between.
Under 30 µA asleep, waking on clock-aligned slots. The sensors are powered only while they are being read.
The cellular link is the expensive part. Readings are collected on one interval and sent in batches on another, so an hourly record can go out once a day.
Both intervals are set from the dashboard. Shorten them during commissioning, lengthen them for the long run, without visiting the unit.
| Battery | Dual 18650 Li-ion, rechargeable |
|---|---|
| Sleep current | Under 30 µA |
| Always on | About two days |
| Hourly readings, one transmission a day | Years |
| Charging input | 6 to 32 V DC, for a solar panel or a fixed supply |
| Operating temperature | -20 °C to +70 °C |
A tank level for delivery planning needs a few readings a day. A cold room alarm needs readings every few minutes. Set the reading interval from that, not from what the hardware can do.
If nobody acts on a reading within the hour, sending once a day loses nothing and saves most of the battery.
Frequent transmission on battery alone is a short life. A small panel on the DC input keeps the cells topped up.
The useful capacity of any lithium cell drops in the cold. In a freezer or a cold climate, mount the controller outside the cold space and run the probe in, or plan for a fixed supply.
An alarm can only fire on a reading that was taken. For points where a fast alarm matters, keep the reading interval short and power the unit accordingly.
It depends on the two intervals you set. Always on is about two days. One transmission a day with hourly readings is years. Everything else sits between the two.
The cells are rechargeable 18650s, charged from the 6 to 32 V DC input. With solar connected they are kept topped up in place.
No. Readings are stored on the device and sent in order on the next successful transmission.
The sensors, how many points, where they sit, and whether there is power and coverage. We come back with whether the ports cover it and what the installation looks like.
