Measures acceleration to find out if an elevator works and updates its status on accessibility.cloud.
This is how the sensor looks:
- 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 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 IoT platform
- Analog Devices ADXL335 3-Axis ±3 g acceleration sensor
- U-blox SARA-U260/U270 3G module for communication with 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)
