This is a simple temperature measurement probe circuit. This circuit measures temperature either on a PC board or at the probe tip to which contains the temperature sensor. It can be used for debugging and troubleshooting electronic circuits. Here is the schematic diagram of the circuit:

Temperature Probe for Digital Multi Meter jadi circuit schematic diagram

This circuit uses the MAX6610 as temperature sensor. We can scale the output to various values by changing the value of R1-R3. This circuit required supply voltage about 3V, so we can use a lithium coin-type cell or two AA alkaline cells. If we use the circuit for board-temperature sensing, the IC must be in intimate thermal contact with the board.

Scale factor of this circuit is? 10mV/°C, and? has ±2°C error over -40°C to 125°C.

This article describes the Temperature Probe for Digital Multi Meter (MAX6610). The content is very simple, very helpful. Components in this article can help you understand better understanding of this article. For example, in this article, you can go to find and buy these components:MAX6610.
