Intelligent wireless low-power air three-in-one sensor:
(1) Capable of collecting indicators: indoor temperature, humidity, and light intensity, model: SWTHL-K500L, air temperature detection range -25-70℃, error ±0.3℃. Air humidity detection range 0-100%, error ±3%. Light intensity detection range 0-120,000 lx, error ±5%.
(2) Using low-power technology and built-in battery power supply, it has a lifespan of up to 3-5 years when measuring and reporting every 15 minutes; it does not use any external wired or solar power supply. (3) Long-distance wireless transmission, with a transmission distance of up to 3 kilometers in open areas;
(4) It integrates three sensors: light, temperature, and humidity, reducing average costs and installation workload.
(5) It has no physical switches, a high level of protection, and has passed the R0HS environmental certification, and does not contain any harmful substances.
(6) The light sensor uses a high-precision silicon photocell measurement circuit, which is much more cost-effective and accurate than solutions using photoresistors or photodiodes.
(7) It has wireless layout, wireless signal transmission, and is self-powered, allowing for the installation position to be adjusted as needed.
