Which sensor is TMP36?

centigrade temperature sensor
The TMP36 is a low voltage, precision centigrade temperature sensor. It provides a voltage output that is linearly proportional to the Celsius temperature. It also doesn’t require any external calibration to provide typical accuracies of ±1°C at +25°C and ±2°C over the −40°C to +125°C temperature range.

How does a temperature sensor TMP36 work?

How It Works: Unlike a thermistor, the TMP36 does not have a temperature sensitive resistor. Instead this sensor uses the property of diodes; as a diode changes temperature the voltage changes with it at a known rate. The sensor measures the small change and outputs an analog voltage between 0 and 1.75VDC based on it.

What is a temperature sensor TMP36?

The TMP35/TMP36/TMP37 are low voltage, precision centi- grade temperature sensors. They provide a voltage output that is linearly proportional to the Celsius (centigrade) temperature.

Is the tmp35 and tmp36 temperature sensors the same?

The TMP35 and TMP36 have the same output scale factor of 10 mV/°C. The TMP37 is intended for an operating range of 5°C to 100°C and provides a 500 mV output at 25°C. This sensor provides a slightly higher precision than the other sensors and has an output scale factor of 20 mV/°C. Output voltage (V) versus temperature (°C). Source: Analog Devices

How many pins does a tmp36 IC have?

The TMP36 do not require any external calibration to provide typical accuracies of ±1°C at +25°C and ±2°C over the −40°C to +125°C temperature range. Low voltage operation (2.7 V to 5.5 V) The IC has just 3 pins, 2 for the power supply and one for the analog output.

What is the temperature of an Arduino tmp36?

Arduino IDE (version 1.6.4+) The TMP36 are low voltage, precision centigrade temperature sensors. They provide a voltage output that is linearly proportional to the Celsius (centigrade) temperature. The TMP36 do not require any external calibration to provide typical accuracies of ±1°C at +25°C and ±2°C over the −40°C to +125°C temperature range.

What should the ADC be on a tmp36 sensor?

At this point you can read the raw ADC value of the TMP36 sensor output. Like the analog I/O guide mentions this value will range from 0 to 65535 proportional to the voltage output by the sensor (from 0 to the analog reference voltage of your board, typically 3.3V to 5V). For example try reading the raw ADC value:
