Easy LM35 Temperature Sensor(SE030)

1．Introduction

This module is temperature sensor with chip LM35, It’s different from other NTC-

MF523950 temperature sensor(ST1147) or DS18B20 temperature sensor(SE029). This

module has one indicator light, which would be on when this module’s voltage signal

is changed. And, this module has integrated 3-pin terminal, which can be simply and

tidily connected with Arduino sensor expansion board, like the following picture:

The Module’s feature as below:
