A low-cost dryer for Alphasense OPC-R1 sensor
Description
The dryer is controlled by an Arduino Uno microcontroller using the RH data of an ambient temperature and RH sensor model HYT221 from iST (Switzerland) and the temperature sensor inside the OPC-R1 (T_OPC). The Arduino Uno controls the heating using a loop: if RH > 65 %, an electrical current will be passed through the wire resistance so that the dryer will be heated. In a second step, the temperature inside the OPC-R1 is used to control the heater. If T_OPC > 35 °C the dryer will be switched off and start cooling down to avoid overheating. Once T_OPC is < 34 °C and RH is still > 65 % the dryer will be switched on again.
