SenseCAP ORCH S4 Features Air temperature/ humidity/ barometric pressure/ light all in one Universal protocols: MODBUS RS-485 or SDI-12 High reliability and stability Wide range power supply: 3.6V ~ 16V Ultra-low power consumption Easy to use, integrate and install IP66 enclosure, suitable for outdoor applications Working in extreme compicate environment Applications Smart Agriculture Smart Cities Smart Industry Environmental Monitoring Other Sensor Applications Introduction The SenseCAP ORCH S4 is designed for the professional environmental monitoring application. It measures and provides reliable data for the customers, even in extreme environmental conditions. The SenseCAP ORCH S4 provides four of the most important environmental parameters, which are air temperature, relative humidity, barometric pressure, and light intensity through a flexible combination. It supports two standard protocols: MODBUS (MODBUS-RTU / MODBUS-ASCII) and SDI-12, with low power consumption and wide range power voltage from 3.6V to 16V. Built-in data pre-processing, therefore customers can quickly complete system development and integration. The Solar Radiation Shield can effectively reduce the impact of solar radiation. which improve the accuracy of detection. The enclosure can protect the device from rain and sunlight exposure, etc. Specifications Air Temperature Barometric Pressure Range -40 to +85 Parameters Condition Value Accuracy 0.2 Range - 300~1100 hPa Resolution 0.1 Resolution - 1 Pa Drift 0.03 /year 700 to 900 hPa Relative Accuracy 0.12 hPa 25 to 40 300 to 1100 hPa Absolute Accuracy 1.7 hPa Air Humidity -20 to 0 Range 0 to 100 %RH 300 to 1100 hPa Absolute Accuracy 1.0 hPa 0 to 65 Accuracy 1.5 %RH Temperature 900 hPa Resolution 1 %RH 1.5 Pa/K Coefficient Offset 25 to 40 C Drift 0.25 %RH/year Drift - 1.0 hPa/year Light Intensity Range 0 to 188000 Lux Accuracy 5% Resolution 0.045 LuxSenseCAP ORCH S4 MODBUS RS-485 General Parameters Power Supply 3.6V ~ 16V Product Model SenseCAP ORCH S4 Vin=16V: 3.6mA (typical) Microcontroller Ultra-low-power MCU Vin=12V: 4.7mA (typical) Interface RS-485 Current Consumption Vin=5V: 11.0mA (typical) MODBUS-RTU RS485/ MODBUS-ASCII Vin=3.6V: 14.5mA (typical) Protocol RS485/ SDI-12 (v1.4) Warm-up Time 250ms (typical) IP66 (water-proof box) IP Rating Scan Interval 1s IPX5 (solar radiation shield) Poll Rate 1Hz Enclosure Material Engineering plastics Response Time 4ms Operating Temperature -40 to +65 Operating Humidity 0 to 100 %RH (non-condensing) Cable Length 2 meters SDI-12 Device Weight 870g Power Supply 3.6V ~ 16V Vin=16V: 40.0A (typical) Current Consumption Vin=12V: 45.3A (typical) (Sleep Mode) Vin=5V: 77.6A (typical) Vin=3.6V: 2.2mA (typical) Certification Vin=16V: 3.04mA (typical) Current Consumption Vin=12V: 3.98mA (typical) (Active Mode) Vin=5V: 8.85mA (typical) Vin=3.6V: 11.80mA (typical) Warm-up Time 15ms Scan Interval 350ms (typical) Device Dimensions Website: www.seeedstudio.com Email: iot seeed.cc Phone: +86 755 3653 4305 AddressF9, Building G3, TCL International E City, Zhongshanyuan Road, Nanshan District, Shenzhen, China. 2008-2020 Seeed Technology Co., Ltd.
