I have the D204B PIR sensor and the BISS0001 chip to work with it. I have reversed the D and S on the sensor and now after fixing it, the circuit in the data sheet (http://cdn.shopify.com/s/files/1/0038/9582/files/BISS0001.pdf) does not work, it just closes the relay even if there is no one in front of the sensor. Do you think I might have damaged the sensor ?
