No Dilemma: Real-Time Data, Instant Alerts, and Longest Battery Life
<< 1µA: Minimal Standby Current
Our battery-powered sensors operate with standby currents in the microampere range, ensuring safe operation for many years. Our engineers are familiar with every single nanoamp (one billionth of an ampere) and know exactly whether it is truly necessary or not. Despite this minimal power consumption, the sensors remain reliably accessible via radio. When not needed, local sensors are completely disconnected from the battery supply and only activated when required. After taking a measurement, they no longer consume any power.
Save Money by Avoiding Useless Telegrams & Data Garbage
Pointless, repeated telegrams cost money and also harm the environment:
- They consume storage space and therefore cost money.
They consume bandwidth and therefore cost money, especially when connecting to the sensor network via mobile data.
They consume energy and thus battery capacity. Batteries need to be replaced, which incurs material and service costs.
Empty batteries place a burden on the environment.
The Solution: Decoupling of Measurement and Transmission Intervals
Each individual sensor in the device can be freely associated with lower, upper, and differential thresholds. This allows measurement ranges to be divided into corridors. Additionally, various intervals can be configured:
- TXT: The fixed transmission interval, example: TXT=3600 (1h). A measurement is taken and sent.
- MSI: The measurement interval, example: MSI=30. A measurement is taken, and only if one of the following conditions is met will a message be sent – otherwise, the device returns to deep sleep:
- >MAX: Too high, example: MAX_TEMP=24.6 °C (temperature)
- <=MAX, >=MIN: Value is within the allowed range
- <MIN: Too low, example: MIN_RH=15% r.h. (relative humidity)
- Delta values (change) per sensor, example: DTEM=1.5K (change from last to current temperature reading)
This combines the longest battery lifetimes with rapid response times. Immediate alert notifications are sent:
- When leaving the configured range in the direction of "Too High", "Too Low", or due to a significant "Change"
- When re-entering the permitted range
Sampling the measurement values consumes relatively little power, so measurement intervals are set quite short (e.g., 10s or 30s). During these intervals, the controller wakes up, takes the respective measurements, and decides—based on the preconfigured thresholds/corridors—whether a notification telegram needs to be sent. If not, it returns to ultra-low-power mode, conserving energy.
If significant changes in values are detected (differential evaluation), a message is also sent, e.g., DBRI=200 lx (change in brightness).
Battery Management
Of course, all battery-powered devices feature intelligent battery management. The local battery voltage is measured under load. If it drops too low, the device will proactively send a "Battery Low" message—long before it becomes unresponsive.
