atai WROTE:Hi can u guys help me..I want to do a temperature and humidity sensing.should I combined PR11 and PR15 or should I only add humidity sensor to PR11.?may i know how to do the modification.TQ
it depends on what you need, PR15 is just displaying the reading, there is no fan output, while PR11 have. Both temperature sensor, LM35 and the humidity sensor is just analog output sensor. Using any microcontroller with analog input can read these sensors.
