STM 330 / STM 330C
Calculations are performed on the basis of electric charges because of the internal linear
voltage regulator of the module. Energy consumption varies with voltage of the energy
storage while consumption of electric charge is constant.
From these values the following performance parameters have been calculated:
Wake

Assumptions:
Internal storage PAS614L-VL3 with 0.25 F, Umax=3.2 V, Umin=2.2 V, T=25 °C
Consumption: Transmit cycle 100 µC, measurement cycle 30 µC
Pre-installed solar cell ECS 300, operating values 3 V and 5 µA @ 200 lux fluorescent
light
Current proportional to illumination level (not true at very low levels!)
These values are calculated values, the accuracy is about +/-20%!
