PlacePod: An STM32 Underground for the Environment and Our Sanity

PlacePod is a smart parking sensor by PNI Sensor that uses an STM32L0 microcontroller (MCU) to help improve battery life. The device is small enough to fit in one hand but still manages to be precise, reliable, and fast. Placed at a parking spot (under or above ground), it detects when a car is parked and immediately sends a signal to a cloud system using a sub-gigahertz network such as LoRa or Sigfox.

Companies can then create applications to guide their users and take advantage of this information, which reduces the time drivers need to find a spot, improving their efficiency and productivity, while reducing their stress levels and their carbon footprint. Finally, the device has a wide range of operating temperatures to ensure that it can function outdoors, regardless of the weather conditions. As a result, PNI already has PlacePods in places like Montreal, California’s Central Valley, and British Columbia…
