# 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

```sh

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

```

# Usage

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

```javascript

const lm35 = require('lm35');

const pin = 26; // ADC0

setInterval(() => {

  console.log(`temperature (in celsius): ${lm35.read(pin)}`);

}, 1000);

```

# API

## read(pin)

- **`pin`** `` Pin number supporting ADC.

- **Returns**: ``

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