Product Manual: Thermistor plug
Introduction Thermistors are normally called NTC resistors. NTC stands for ‘Negative Temperature Coefficient’. Thermistors are basically variable resistors whose resistance decreases with the increase in temperature. They are primarily used as resistive temperature sensors. Elint Labz has built a plug using NTC and a pull down resistor circuit. NTC plug can be mounted anywhere using screws. This PCB design has a flexibility to bend the thermistor in any position.

Details Thermistor plug is an analog input device to the interfacing system. It has a interfacing port with three pins denoted as G, V and D. Here G represents Ground , V represents VCC and D represents Data pin through which NTC thermistor analog values can be obtained. These analog values can be mapped to determine the temperature.
How to interface?
Use either of the supported interfacing cables to connect thermistor sensor plug to the controller board. If 4-3A cable is to be used then 3pin end of the cable is connected the thermistor sensor plug and 4pin end of the cable must be connected to the controller board. If 3-3A wire is to be used then any end of the cable can be connected to the thermistor plug. Always ensure that black wire of the cable is connected to the G pin on both ends. In the below pictures one can see 4-3A cable is used to connect Thermistor plug to the Pluguino Board. The data pin of the thermistor plug can be connected to any one of the analog pin on the controller board. Here thermistor plug is connected to A0 pin of the controller board.

Example Code Code 1: Arduino Objective: Increase the temperature of the thermistor by bring a lit matchstick near it and reading the analog values from the data pin and printing it on the serial monitor. #define THERMISTOR_PIN A0 analog pin A0 void setup() { Serial.begin(9600); }
// connecting Thermistor to the
