who knows those components from a weather station ? Answered


Yellow eggs are capacitors, probably tantalums.
Part with the glass window is probably a photo diode.
Little blue thing is a thermistor

thanks for your answer
but there is no glass window, it's like jelly inside ...

this weather station only give t° and relative humidity

tada! Humidity sensor :)

be advised, humidity sensors are affected by light level -- hence the goop is probably opaque. If it's an aqueous jelly it will change more slowly than the air humidity, slowly adapting to the new condition.

thanks a lot
any ideas where to find datasheet for this kind of sensors

I bet it would be very similar to any generic humidity sensor, with the characteristic output curve being the main difference -- the operation should be very similar.
