Industrial-Grade Optical Rain Gauge RG-15 Rain Sensor

Industrial-Grade Optical Rain Gauge RG-15 measures rainfall volume and intensity accurately and reliably. It features easy installation and is maintenance-free, suitable for multiple applications that require rainfall data monitoring. It can also be used with the SenseCAP LoRaWAN® Data Logger to easily connect with the local LoRaWAN® network, enjoying the benefits of low-power and long-range communication. Features

• Industrial-grade design: High reliability with a rugged surface, provides accurate measurements
• User friendly: Can be easily installed on weather station masts, buildings, and other infrastructures
• Maintenance-free: No debris would be generated and no clogging in the gauge
• Wide application scenarios: Can be used in various scenarios like hydrological network monitoring, irrigation control, climate studies, etc.

Description Rainfall volume provides important information for people's decisions and actions in weather and climate studies, hydrological network monitoring, agriculture, food delivery, and many other industries. In the agriculture scenario, with the precipitation information accessible, farmers can make sound decisions for the irrigation schedule and amount, ensuring sufficient water for crop growth, and avoiding waste of water, root rot, or other diseases.     This industrial-grade Optical Rain Gauge RG-15 is a perfect fit for rainfall measurement. It's a reliable, cost-effective, and rugged rain gauge that uses light beams to determine how much rain has fallen at what intensity. It uses beams of infrared light within a plastic lens about the size of a tennis ball. With the round surface of the lens, there are no collections of debris, no moving parts to stick, or water pathways to clog.     The RG-15 Optical Rain Gauge features an open-collector output that emulates a conventional tipping bucket, as well as serial communications that provide more detailed data and allow for the configuration of the device. It can be configured through the serial port, or optionally via DIP switches. A built-in mounting arm allows for convenient mounting to weather station masts, buildings, and other infrastructure. It's also suitable for solar-powered applications.   Applications

• Smart Agriculture
• Smart City
• Climate Studies
• Hydrological Network Monitoring
• Condensation and Frost Sensing
• Irrigation Control 
• Drop Detection
• Wiper Control
