What is TMP36?
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 accurate is TMP36?
Reading temperatures to 0.1 degree precision!
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 are the 3 pins of the temperature sensor TMP36?
The TMP36 has three pins. Looking at the flat side of the sensor the leftmost pin is Voltage in (between 2.7V to 5.5V DC). The center pin is Voltage out. This puts out a variable voltage between 0.1V (-40°C) to 2.0V (150°C), and will connect to any of the Analog input pins on the Arduino.
Why are LDRs connected to analog pins?
This system works by sensing the intensity of light in its environment. That is, the greater the intensity of light, the greater the corresponding voltage from the LDR will be. Since the LDR gives out an analog voltage, it is connected to the analog input pin on the Arduino.
Is the tmp36 compatible with the LM50?
The TMP36 is specified from −40°C to +125°C, provides a 750 mV output at 25°C, and operates to 125°C from a single 2.7 V supply. The TMP36 is functionally compatible with the LM50.
What is the output of the tmp36 temperature sensor?
Output range: 0.1V (-40°C) to 2.0V (150°C) but accuracy decreases after 125°C Using the TMP36 is easy, simply connect the left pin to power (2.7-5.5V) and the right pin to ground. Then the middle pin will have an analog voltage that is directly proportional (linear) to the temperature.
What kind of surface mount is the tmp36?
The TMP35/TMP36/TMP37 are available in low cost 3-lead TO-92, 8-lead SOIC_N, and 5-lead SOT-23 surface-mount packages. At least one model within this product family is in production and available for purchase.
Do you need to calibrate the tmp35 or tmp36?
The TMP35/ TMP36/TMP37 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. The low output impedance of the TMP35/TMP36/TMP37 and its linear output and precise calibration simplify interfacing to temperature control circuitry and ADCs.
