The project described here is a switch mode fan speed controller for use with brushed or brushless DC motors. Temperature proportional speed control is accomplished using pulse width modulation (PWM). 10K Ohms NTC is used to sense the temperature. The project is built using TC648 chip...

This Li-Po/Li-ion Arduino charger shield is mainly designed to power up the Arduino from single 3.6V Li-Po battery. Li-Ion and Li-Pol Charger/ DC-DC Boost converter Arduino shield provides 6.5V/400mA from single Lithium Polymer battery. The Arduino shield is equipped with BQ21040...

This 3 in 1  shield for Arduino Nano helps to develop various temperature measuring applications. Arduino Nano shield consists of 3 different types of temperature sensors. MLX90614 non-contact temperature sensor 10K NTC Analogue Temperature Sensor Programmable Resolution...

Philip Kane @ jameco.com discuss about how to measure temperature with NTC thermistors. He writes: Thermistors (thermal resistors) are temperature dependent variable resistors. There are two types of thermistors, Positive Temperature Coefficient (PTC) and Negative Temperature...

Ahmad Al-Shalabi and Bassma Karbouj show us how to control a DC fan using easy to find components. The fan works when temperature reach into pre-specified threshold. The purpose of this project is creating a cooling system by controlling in a DC fan in a simple way without using...
