After cutting and grounding the tips of passive and active sensors, the 100 Hz noise is move away. For measuring the clamp temperature, the chip TMP01F from Analog Devices is used.

Meanwhile we received a new sensor from Vereta, which is now a so called "Gefühltetemperatur Sensor" or perceived temperature sensor. The output are two linear voltages 0 - 5V DC represented air and perceived temperature 25 – 37 Celcius.

Now I jump to MICA programming as it is almost 3 months working on the sensor hardwares. The TinyOS Tutorial is available here.
