(current for external sensor circuits not included)
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 typical performance parameters at room temperature have
been calculated:

Assumptions:

Internal storage PAS614L-VL3 (after several days of operation at good illumination
level) 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!)
