6.1 Connect STM 312 with ECT 310 Perpetuum and Peltier element

Solder output pins of the ultra-low voltage converter ECT 310 to the power
input pads on the backside of STM 312 sensor

Peltier element to the input pins of ECT 310

For details and pin layouts see STM 31x user manual
6.2 Demonstration

Expose the Peltier element to a heat flux of more than 1-2 °C temperature
difference between cold and hot side.

With an ambient temperature of about 20°C it is enough to hold the finger
on top of the “hot” side of the Peltier element. This causes enough energy
to power STM 312 and send several telegrams.

In order to generate a permanent heat flux we recommend to use a heat
spreader on the cold side and a hot surface e.g. heating system, hot en-
gine etc. on the hot side.

