    Default Temp & Humidity sensor interfacing question

    Hi everyone, I got a Grove Temp & Humidity sensor....according to this link "http://www.seeedstudio.com/wiki/Grove-_Temperature_and_Humidity_Sensor" I need to send signal to trigger and should give 40 bits of data. From the attached image D1 is the communication line...please correct me if I'm wrong, All I need to do is send binary 1 to D1 and the 40 bits will coming out from the sensor? Hope anyone can give me a hint.... I'm planning to use Pic18F44550 and I'm using PBP2.60.thanks in advance,tacbanon
