Gravity: Analog LM35 Temperature Sensor for Arduino

The Gravity Analog LM35 Temperature Sensor is a straightforward ambient air temperature sensor designed for Arduino and ESP32 development boards. Featuring a linear 10 mV per degree Celsius analog output, it allows direct reading via an analog-to-digital converter without complex libraries or digital communication protocols. It is ideal for students, educators, and makers learning basic electronics or building indoor environmental monitoring projects.

Linear analog voltage output

The module utilizes a semiconductor LM35 chip with a linear sensitivity of 10 mV per degree Celsius over a 0 to 100 degrees Celsius operating range. This enables direct voltage-to-temperature conversion through microcontroller ADC inputs without requiring I2C or UART communication.

Simple wiring with Arduino

Operating on a wide 3.3V to 5V supply, the sensor connects seamlessly to 3.3V and 5V microcontrollers using the standard Gravity analog pinout. The included analog cable ensures plug-and-play wiring to your prototyping setup.

Built for education and prototyping

By providing a direct analog signal path, this board offers a clear, practical platform for classroom ADC experiments and sensor fundamentals. It is best suited for measuring ambient air temperature in dry indoor environments.

Durable Gravity mounting standard

The circuit board features an immersion gold finish, high-quality connector, clear analog port labelling, and standard 5 mm pitch mounting holes for secure mechanical assembly.

Included in the package

The kit includes one LM35 analog temperature sensor module and one dedicated Gravity analog sensor cable.
