Building construction monitoring and security system

Whether during construction or in use, civil construction projects require real-time health monitoring of the building structure, such as inclination changes, wall subsidence displacement, support pressure, concrete solidification temperature...

Traditional monitoring methods generally use on-site Wiring, manual scheduled patrols, and on-site reading with handheld instruments, the use of IoT technology is seriously insufficient. Therefore, this project will use LoRa networking and IoT technology to implement wireless and automated building monitoring applications.

XDPL8105 40W Reference Design

The XDPL8105 40W reference design is a digital ground configured LED driver with a universal input of 90-305 V AC, a wide output load range of 16-45VDC and isolated 0-10V dimming based on a CDM10V dimming IC. The power stage uses IPD80R1K4CE, a 900mOhm CoolMOS™ CE power MOSFET. 

Open source power meter: with power supply function, dedicated to IoT power consumption measurement

The biggest feature of testing the power consumption of IoT devices is the high dynamic range, a few uA in the sleep state and hundreds of mA in the transmitting state, and it supports dynamic switching of the measurement range. The open source power meter ZS1100A has a dynamic measurement range of 1uA to 1.5A, a resolution of 100nA, and an accuracy of 1% ± 200 nA, which is very good.
