A Low-Power Solution To Streamlining Sensor Data For IoT

For home use IoT systems, getting sensor data from tons of physical locations centralized to a single Raspberry Pi can be a difficult job, especially when considering the power consumption that’s necessary for doing it all over WiFi. When you’re using an ESP8266, for instance, swapping out batteries and accounting for connectivity issues can be a major hassle for a long-term solution. The NoCAN platform, created by [Alain Pannetrat], solves this problem using a wired approach that improves the use of the CAN bus.

Since SPI and I2C only work for short distances, approaches like RS-485 and CAN bus are a better bet for this type of setup. For systems with one centralized point, RS-485 works best – thus, the CAN bus is the better approach when you’re considering using multiple masters in a single environment.
