SenseCAP ORCH S4 is an Air Temperature / Humidity / Atmospheric Pressure / Light four-in-one weather instrument featuring solid performance, ultra-low power consumption, and easy installation. It integrates 4 sensors to monitor parameters of air temperature, humidity, barometric pressure, and light intensity. With strong robustness, it is particularly suitable to operate in severe environments both indoors and outdoors. This version (A1B) comes with a waterproof aviation connector, saving you time and effort in connecting the sensor to a data logger with hook-up wires and screws.
This weather instrument supports two universal standard protocols: MODBUS (MODBUS-RTU/MODBUS-ASCII) and SDI-12. With a wide range of power voltage from 3.6V to 16V and ultra-low power consumption, ORCH S4 has ensured durability to maintain long-term meteorological monitoring. The built-in data pre-processing enables users to unlock and complete new system development and integration in a convenient manner. This weather transmitter also comes with a solar radiation shield which effectively reduces the impact of solar radiation, thus further guaranteeing data accuracy. As an industrial-grade product, its IP66 enclosure also protects the sensors from rain, dust, and UV.
As an indispensable component of weather stations, ORCH S4 meteorological sensors can be widely applied to a variety of environments, including smart agriculture, smart city, smart building, etc. This product has been deployed in strawberry greenhouses in Shandong Province in northern China with great customer feedback.
