LM35

Kaluma library for LM35 temperature sensor.

Wiring

Here is a wiring example for ADC0.

Raspberry Pi Pico	LM35
VBUS (5V)	VCC
GND	GND
GP26 (ADC0)	OUT

Install

npm install https://github.com/niklauslee/lm35

Usage

Here is an example code for reading temperature (in celsius) from LM35.

const lm35 = require('lm35');
const pin = 26; // ADC0

setInterval(() => {
  console.log(`temperature (in celsius): ${lm35.read(pin)}`);
}, 1000);

API

read(pin)

• pin <number> Pin number supporting ADC.
• Returns: <number>

Reads voltage from the pin and returns temperature value in celsius.
