Build IoT applications
with TypeScript

Deploy code to your devices in minutes. Control hardware from anywhere. Update firmware over-the-air. All with the tools you already know.

src/devices/sensor.ts
import { DeviceEntrypoint } from "@devicesdk/runtime";

export default class Sensor extends DeviceEntrypoint {
  async onDeviceConnect() {
    // Monitor temperature sensor every 5 minutes
    await this.env.DEVICE.configureAdcMonitoring(26, {
      interval: 300000
    });
    this.env.logger.info("Sensor monitoring started");
  }

  async onMessage(message) {
    if (message.type === "adc_reading") {
      const temp = this.convertToTemperature(message.payload.value);
      await this.env.DEVICE.kv.put("temperature", temp);
    }
  }
}
