KQS-CSM MINI Ultrasonic Environment Monitor
The KQS-CSM MINI is a cost-effective micro weather monitoring instrument featuring low-power chips and circuit design. With standard 5-element power consumption of only 0.2W, it's ideal for solar or battery-powered applications. The compact design measures approximately 8cm in diameter and 10cm in height, integrating wind speed, wind direction, temperature, humidity, barometric pressure, and optional elements into a single compact structure. All parameters output via RS485 digital interface for 24-hour continuous outdoor monitoring, with optional low-temperature heating available.
