LD-CO2/A

LD-CO/A is a wireless passive carbon monoxide sensor, a solar powered free maintenance, no wiring, energy storage module can store solar energy, even if it is completely dark, it can work continuously for 4 days, and the external power supply. The sensor is small and sends CO data and temperature data messages every half an hour. When the CO concentration increases, it detects, speeds up and transmits wireless signals.
