LM35 temperature sensor - analog, -55 to +150 °C, XH2.54 3P

Product Overview

• Analog temperature sensor with calibrated output voltage
• Measuring range −55 °C to +150 °C
• Accuracy ±0.5 °C
• Power consumption maximum 60 mA
• XH2.54 3P socket for a secure plug connection
• Linear voltage-temperature relationship with no calibration required

Product Description

This temperature sensor converts heat directly into proportional voltage values. The sensor requires a power supply between 4 V and 30 V and outputs a voltage at its output pin that corresponds to the measured temperature, with each Kelvin corresponding to a voltage change of 10 mV. This allows microcontroller boards with an analog input to read temperatures directly without complicated conversions.

The measurement remains reliable across the temperature range of −55 °C to +150 °C with an accuracy of ±0.5 °C. The voltage output allows direct connection to most common development boards, provided their supply voltage is within the operating range. Power consumption remains low at a maximum of 60 mA.

The XH2.54 3P socket enables quick plug connections without soldering. This is particularly useful in prototypes and test setups where sensors are frequently replaced or repositioned. Typical applications include temperature monitoring in electronics projects, measurement data acquisition for ambient climate control, laboratory setups for investigating heat conduction, or temperature control in homemade incubators.

The sensor's power supply must be provided separately and is outside the typical 5 V or 3.3 V logic voltages of microcontroller boards. When used with 3.3 V logic inputs, the voltage output signal must be routed through a level shifter to prevent damage.

Safety Notice

This sensor is intended exclusively for building prototypes and for testing and development purposes. It is not suitable for installation in household electrical circuits or in devices designed for mains voltage operation. If you are unsure about the operating voltage or wiring, consult a qualified electrician before commissioning.
