Orch S4 Weather Sensors

Product Description

ORCH S4 is an Air Temperature / Humidity / Atmospheric Pressure / Light four-in-one compact weather instrument featuring solid performance, ultra-low power consumption, and easy installation. It integrates 4 sensors monitoring parameters of air temperature, humidity, barometric pressure, and light intensity. With strong robustness, it is particularly suitable to operate in severe environments both indoor and outdoor.

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 guarantees data accuracy. As an industrial-grade product, its IP66 enclosure also protects the sensors from rain, dust, and UV.
