I2C Sensors

Read temperature, humidity, and pressure from I2C sensors like BME280.

Sensor Toolkit

Read I2C sensors on Raspberry Pi — temperature, humidity, and barometric pressure from BME280 and similar sensors.

Requires i2c-bus as an optional peer dependency.

Quick Start

import { Agent, ollama } from "@radaros/core";
import { SensorToolkit } from "@radaros/edge";

const sensor = new SensorToolkit({ busNumber: 1 });

const agent = new Agent({
  name: "weather-station",
  model: ollama("llama3.2:1b"),
  instructions: "Read environmental data from sensors and report conditions.",
  tools: [...sensor.getTools()],
});

const result = await agent.run("What's the current temperature and humidity?");

Config

I2C bus number. Standard on all Raspberry Pi models is bus 1.

addresses.bme280 · number · default: "0x76"

I2C address for the BME280 sensor.
