It is quite likely that you have an MTS310CB board (look for a jumper
wire on the bottom-side of the sensor board). 
The MTS310CA uses INT2 for temperature power control where as the CB
version uses PW0. It sounds like you are using CA code on CB hardware
and hence the Temp sensor never gets turned on and returns 0.
The software modification involves changing one line of code. In
sensorboard.h file of the app, change 
    TOSH_ALIAS_PIN(TEMP_CTL, INT2) to TOSH_ALIAS_PIN(TEMP_CTL, PW0) 
Recompile and reprogram the Mote attached to the Mote. You should be
able to read the correct temperature value now.
 
I hope that helps,
Giri

I mean the ADChannel input that you are reading is grounded.

 

Sorry,

Sounds like your temperature sensor output is grounded on the board?

Dear all,

I am having some problem with the temperature sensor value that I am
getting from MTS310 sensorboard. I am using Crossbow's
contrib/xbow/apps/XSensorMTS300 application. This application reads ,
among other things, the temperature sensor value. My problem is I always
get 0 from  Temperature.dataReady(uint16_t data)  event. Please note
that I am using micaz and tinyos 1.1.11. But when I remove the MTS310
board from the micaz mote, the temperature reading that I get is not 0.
Please let me know what I am missing here.

Thanks a lot,
Monica
