Environmental monitoring sensor Seeed 101991044 featuring Modbus RTU and SDI 12 communication protocols
Product Overview
The SenseCAP ONE is a series of all-in-one compact weather sensors designed for comprehensive environmental monitoring. These devices integrate multiple sensors to measure up to 10 weather parameters including air temperature, humidity, atmospheric pressure, light intensity, wind speed, wind direction, precipitation, PM2.5, PM10, noise, and CO2. Utilizing ultrasonic technology for wind measurement, the SenseCAP ONE offers high-precision data collection and low maintenance. Engineered to industry standards, it operates reliably in harsh outdoor environments across a temperature range of -40C to 85C and supports Modbus-RTU (RS485) and SDI-12 communication protocols.
