Summary

This circuit is designed to control a DC motor based on the temperature readings from an LM35 temperature sensor. The circuit uses a BC547 transistor to switch the motor on and off, with power supplied by a MAHIR 1.mini power source.

Component List

1. Temperature Sensor (LM35)

   • Description: The LM35 is a precision integrated-circuit temperature sensor, whose output voltage is linearly proportional to the Celsius temperature.
   • Pins: +Vs, Vout, GND

2. DC Motor

   • Description: A simple DC motor that converts electrical energy into mechanical motion.
   • Pins: pin 1, pin 2

3. BC547 Transistor

   • Description: The BC547 is an NPN transistor used for general-purpose low-power amplifying or switching applications.
   • Pins: Collector, Base, Emitter

4. MAHIR 1.mini

   • Description: A power source providing 3.7V and GND connections.
   • Pins: GND, 3.7v
