Indoor Air Quality (IAQ) Sensor
KS61 -Indoor Air Quality (IAQ) Sensor
KS61 is a set of multi-functional and sophisticated design in one of the 86 type wall switch type indoor environment monitoring sensor. It can monitor PM2.5 (zero fire version support), temperature, humidity, light intensity, CO₂, TVOC and human movement (PIR) and other environmental parameters in real time, and is equipped with electronic ink screen, which supports local intuitive view of air quality data, and the information is clear and easy to read.
KS61 adopts standard 86 box size design, built-in three physical buttons, easy to install, can directly replace the traditional wall switch. After the remote control function is enabled, the user can realize the intelligent control of the switch on and off through the network, taking into account the local operation habits and remote intelligent management.
The product is based on LoRa ® Wireless technology, supports standard LoRaWAN ® Protocol, with the advantages of long-distance communication and ultra-low power consumption, is suitable for large-scale, long-life IoT deployment scenarios. KS61 compatible with ManThink and third party LoRaWAN ® Gateway, and seamless access to ThinkLink, ChirpStack, The Things Network(TTN) and other mainstream Internet of Things platforms, easy to achieve environmental data collection, remote monitoring, intelligent analysis and energy-saving linkage control, widely applicable to smart office, smart home and building management system.
