SKU_BOS0011_Temperature_Sensor

Introduction

There are four types of commonly-used temperature sensors: thermocouple, RTD(resistance temperature detector), thermistor, and semiconductor. Normally, the thermocouple provides the widest measurement temperature range from –184ºC to +2300ºC. The resistance temperature detector offers a fairly linear output that is highly accurate across –200ºC to +850ºC and the later two kinds are suitable for temperature measurement below 200℃. Semiconductor sensors usually have relatively high accuracy.
Temperature sensing is one of the most sensitive properties or parameters for industries like petrochemical, automotive, aerospace and defense, consumer electronics, and so on.

Specification

Connector: PH2.0-3P
Product Dimension: 22×26(mm)/1.02×0.87"
Signal: analog

Pinout

Pinout BOS0011

Label	Name	Description
1	GND	Ground
2	VCC	Power Input
3	SIGNAL	Analog

Usage Description

The temperature sensor can be used to detect the environmental temperature and convert the temperature into an analog electrical signal. The output signal increases as the temperature rises.

Principle

The temperature sensor is based on the principle that the resistance of NTC changes with temperature. It converts physical quantities into electrical signal so as to accurately detect temperature.

Application

1. Air Temperature Detector

Description: Put two pots of plants with same growth under different temperature conditions. Record their growth situations.

(3) Temperature Indicator (Programming)

Description:

When the temperature is detected to be below 25℃，the green LED turns on. If the temperature is within 25℃to 35℃, the blue LED turns on, if temperature over 35℃, the red LED turns on.
