The GND pin is connected to the substrate, and therefore has the least thermal resistance between temperature sensor and heat source.Figure 1. It has more complete and accurate performance than the basic version. The TMP35/TMP36/TMP37 are low voltage, precision centigrade temperature sensors. A silicon temperature sensor is an integrated circuit, and can, therefore, include extensive signal processing circuitry within the same package as the sensor. Its features make it suitable for many general temperature-sensing applications. They provide a voltage output that is linearly proportional to the Celsius (centigrade) temperature. They’re analog sensors, so the code is relatively simple compared to digital temperature sensors that require special libraries and lots of code. A Voltage Output Temperature Sensor provides an analog output signal of varying voltage on a single pin. For example 2V could mean 25 degrees celsius from an analog temperature sensor. The KY-013 Analog Temperature Sensor module consist of a NTC thermistor and a 10 kΩ resistor. The trip temperature (T TRIP) is programmable by using two external 1% resistors.
