HPM155 Vaisala


Adil Sep 30, 2025 09:55 AM

Hi all,
I am new to using Campbell data loggers. I have a Vaisala HMP155 sensor with a 0–1V output and a Campbell CR6 data logger. I would like to connect the sensor to the data logger. Could anyone suggest a program for this setup?
Please note that the connector is 8-pin. The details are as follows:
HMP155ACBL1 Cable provided by Campbell Scientific:
VOUT1 (yellow, temp)
No connection
AGND (white)
VOUT2 (blue, RH)
No connection
No connection
VCC (red)
GND (black)– Shield (clear)
Additionally, could you please provide the pin diagram?

You can use the Short Cut program generator. The program generator assumes you purchased the sensor through Campbell Scientific, so the temperature range is expected to be set to -40 to +60C. If purchased direct from Vaisala, the temperature range may be different and require a different multiplier and offset.

Thanks for your response. Yes, I have tried, but the issue is that I have an 8-pin cable, while the shortcut shows a 6-pin sensor.
