Sigfox IoT Device
Budget: $6,000 – $12,000 HKD
This project involves developing hardware and software. The device is based on 3 key components, a broadcom APDS-9250, a STM32 MCU and a Sigfox transceiver. Together these components will count the pulses of a flashing LED over a 1 hour period, then transmit the count over the Sigfox network.
The basic components have been tested. I have built several prototype devices that use the APDS-9250 and transmit the count vis Sigfox. This device is going to be battery powered, this specific version that you are going to design is going to be field tested so I can understand the power requirements of a working prototype.
In the last month a Freelancer I engaged (on a different platform) disappeared without shipping me the finished article, I have included photos of that device for reference, but I don't have the actual device. I have created a PDF giving a bit of an overview of the requirements, feel free to ask any questions.
I am a refrigeration technician by trade and although I have a working knowledge of electronics, I am by no means an expert and have no formal qualifications, so I will apologies in advance if I can't fully answer answer some questions!
