I am attaching the raw values for temperature and voltage
These are the values from our modified Delta (where we also send
humidity and voltage with DeltaMsg).
So in our nesC we are taking all three values (temp, humidity, and volt)
as in the code below:
async event result_t Humidity.dataReady(uint16_t data) {
humidity = data;
call Temperature.getData();
return SUCCESS;
}
event result_t HumidityError.error(uint8_t token) {
humidity = 0;
call Temperature.getData();
return SUCCESS;
}
async event result_t Temperature.dataReady(uint16_t data) {
temperature = data;
call InternalVoltage.getData();
return SUCCESS;
}
event result_t TemperatureError.error(uint8_t token) {
temperature = 0;
call InternalVoltage.getData();
return SUCCESS;
}
async event result_t InternalVoltage.dataReady(uint16_t data) {
ivolt = data;
post sendData();
return SUCCESS;
}

Can you post your raw data, including timestamps?

Hello,
we are trying to get temperature, humidity and voltage from Tmote Sky.
We are using the Delta application.
For the temperature we are reading Sensirion Humidity and Temperature
sensor. At the base station we are using the
indicated formulas to convert to meaningful Celsius degrees:
temperature = -39.60 + 0.01*SOt
where SOt is the value we get from the sensor.
The result is like 37 C where it should be 32 C. So we have a big
difference. Are we doing something wrong?
Also for the voltage, we are measuring the value from the mote attached
to the USB (so the value should be 3V) but we get 2.3 V
We are using the formula
value/4096 * 1.5 * 2
Again, what is that we are doing wrong? We get the same results if we
place new batteries to a mote.
Thanks in advance,
Ioannis.
