Watchible is an NB-IOT add-on board for the Raspberry Pi Pico. It is low cost, and low power. It is meant to monitor any trigger with a low impedance interface. Both the Pico and the Quectel BCC-66 modem can be put to sleep for up to 12 hours, and will wake up if an alarm is triggered. This reduces power consumption and allows Watchible to be in remote locations, powered by a simple battery for months or years, depending on how big the battery is and how many times it has tow wake up to insure a connection to the network. With other add on boards the number of things that can be monitored is limitless. Examples are remote water detection, gas sensors, and any kind of switch.. The board can be used in fault analysis in remote places like buildings or bridges, using ultrasonic or vibration analysis.

Because it sits on the Raspberry Pi Pico It can easily be programmed to use any cloud IOT service, such as AWS, Azure, Google, or HiveMQTT. It can be programmed in C/C++ and Python. When placed in a hardened enclose the Watchible provides a small profile remote monitor that can be placed any where and simple run with little to no maintenance.

I developed this to be water detector for my boat after my son's boat sank at a Marina. I have talked with many people about different uses and I believe there is a definite need for this device, in all kinds of monitoring situations. This board is a better alternative to LoRa networks which require gateway build out and testing and much more maintenance, and have a single point of failure should the gateway fail. While it is not specified in NB-IOT applications, I have also tested it on a moving vehicle, and it worked.

I believe there is a huge market for this board as IOT applications become more prevalent. I hope will consider the project
