This module provides a simple breakout for the sensor, requiring only a single analog input pin to read temperature. With 10mV per degree Celsius scaling, it’s plug-and-play for microcontrollers and ideal for environmental monitoring, HVAC prototypes, and educational projects.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Scale\u003c\/td\u003e\n\u003ctd\u003e10 mV per °C\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTemperature Range\u003c\/td\u003e\n\u003ctd\u003e0°C to 100°C\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eAccuracy (25°C)\u003c\/td\u003e\n\u003ctd\u003e±0.5°C\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e4V to 30V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eAnalog voltage\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCurrent Drain\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;60 µA\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-server-room-temperature-monitor-kit-v4\"\u003eRoom temperature monitor with LCD display\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eArduino-based thermostat with relay control\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-indoor-weather-station\"\u003eMulti-sensor weather station for ambient logging\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-sd-card-data-logger\"\u003eBattery-powered temperature data logger with SD card\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThe LM35D module works with any board having an analog input. Use it with Arduino Uno, Nano, or Mega by connecting the output to A0. ESP8266 and ESP32 require an ADC pin (ESP32 ADC is 12-bit). Raspberry Pi needs an external ADC like MCP3008. The sensor outputs 0–1V for 0–100°C, so 5V tolerant ADCs read directly without level shifting.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect VCC to 5V (or 3.3V if within supply range) and GND to ground. The OUT pin connects to an analog input. For stable readings, add a 100nF capacitor between VCC and GND near the sensor. Avoid long wires in noisy environments to prevent parasitic oscillations.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
