Adding a thermometer to your digital multimeter
Reading ambient temp is useful in electronics, and reading it from your handy multimeter is even better. Raj added a thermometer feature to his DMM, by hard-wiring it into the case. He used an LM35 analog temperature sensor and a slide switch connected to the multimeter inputs. You just flip the knob to the 200mV range and slide the switch to get the readout.
