# liftsensor

Measures acceleration to find out if an elevator works and updates its status on [accessibility.cloud](https://www.accessibility.cloud).

## Technical specification

- Plug & Play installation using the maintenance 230V AC connector on top of the elevator's cabin

- Typical power consumption <1W, micro USB power adapter

- Sets the elevator's status to 'unknown' on [accessibility.cloud](https://www.accessibility.cloud) if it has not been in use within typical usage time intervals

- M2M Nano SIM card leverages a comprehensive network of carriers to provide service in over 100 countries out of the box

- Built-in 150mA battery to actively send a maintenance event in case the device is actively unplugged

- Open source design based on [Particle Electron](https://docs.particle.io/datasheets/electron-(cellular)/electron-datasheet/) IoT platform

- Analog Devices ADXL335 3-Axis ±3 g acceleration sensor

- U-blox SARA-U260/U270 3G module for communication with [accessibility.cloud](https://www.accessibility.cloud)

- STM32F205RGT6 120MHz ARM Cortex M3 microcontroller

- 1MB flash, 128KB RAM

- Allows firmware updates over-the-air

- RGB status LED

- Real-time operation system (RTOS)
