The RSA is a rain sensor with a processor controlled relay contact and surface temperature control and is ideal for climate control systems such as sun blinds and greenhouse automation.

For even better climate control we have the programmable sensor RSA-P. This reliable rain sensor can be programmed en read out on PC by the user
