liftsensor\n\nMeasures acceleration to find out if an elevator works and updates its status on [accessibility.cloud](https://www.accessibility.cloud).\n\n## Design / photos\n\nThis is how the sensor looks:\n\n![image](./docs/case-open.jpg)\n![image](./docs/case-with-lid.jpg)\n![image](./docs/case-photo.jpg)\n\n## Technical specification\n\n- Plug \u0026 Play installation using the maintenance 230V AC connector on top of the elevator's cabin\n- Typical power consumption \u003c1W, micro USB power adapter\n- 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\n- M2M Nano SIM card leverages a comprehensive network of carriers to provide service in over 100 countries out of the box\n- Built-in 150mA battery to actively send a maintenance event in case the device is actively unplugged\n- Open source design based on [Particle Electron](https://docs.particle.io/datasheets/electron-(cellular)/electron-datasheet/) IoT platform\n- Analog Devices ADXL335 3-Axis ±3 g acceleration sensor\n- U-blox SARA-U260/U270 3G module for communication with [accessibility.cloud](https://www.accessibility.cloud)\n- STM32F205RGT6 120MHz ARM Cortex M3 microcontroller\n- 1MB flash, 128KB RAM\n- Allows firmware updates over-the-air\n- RGB status LED\n- Real-time operation system (RTOS)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fopyh%2Fliftsensor","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fopyh%2Fliftsensor","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fopyh%2Fliftsensor/lists"}
