[AVR club] How to measure temperature. - n.na...@gmail.com - Jun 9 8:31:06 2008
Hi all. I am working with ATMEGA169 microcontroller. I am using a battery to provide supply to the board.I am uisng ISL6292 battery charger. A TEMP pin of the charger monitors the battery temperature to ensure a safe charging temperature range. This TEMP pin is connected to ATMEGA. Some voltage is appearing on this pin from this voltage how to calculate the temperature.

Re: [AVR club] How to measure temperature. - Zack Widup - Jun 9 8:36:20 2008
I don't quite understand the setup. What actually measures the
temperature? Does the ISL6292 have a temperature measuring device built
in that outputs a voltage on the TEMP pin? If that's the case, you just
need to set up one of the A/D converters and use it to measure the
voltage coming out of the 6292.
The data should all be in the data sheets for the respective parts.

Read the data sheet for starters:

The TEMP pin is not to be connected to the AVR but to an NTC resistor
mounted on your battery. If you want to measure temperature I strongly
suggest you stay off this signal and put your own NTC where ever, or use
a purpose-designed factory calibrated temperature module/chip.

The temperature sensor in this device is designed to measures the
temperature of the charged battery. Once they reached a specific
temperature it will shut off. Kind of like a safety feature
If you just want to measure ambient temperature look into the
DS18B20 , DS1820 etc. They are One Wire connections and have plenty of
programs for AVR MCU's that cover them.

Dear Nandini,
=A0 If some voltage is appearing then in the datasheet it should mu=
st be given that how much rise in temp equals the voltage for ex LM535 temp=
sensors from Natioanal semi.So check D/S of your Bat charger.For any clari=
fication write to me ASAP.
Nandini, where are you working? can you help me, u can!
can you send me a circuit of power supply particularly using Micros like ti=
ny and mega. I need this one. pls help me out!
