The integrated photocell provides day\/night detection for the GCS-1, while temperature, humidity and CO₂ readings provide the environmental data required for climate-based automation. This listing is the standalone replacement sensor for an existing GCS-1 system.\u003c\/p\u003e\n\n\n\u003cp\u003e• SKU: MBS-GH\u003cbr\u003e\n• Brand: TrolMaster\u003cbr\u003e\n• Compatible Controller: Green-X GCS-1\u003cbr\u003e\n• Parameters Measured: Air Temperature, Relative Humidity, CO₂ PPM and Photocell (Day\/Night)\u003cbr\u003e\n• Connection Interface: RJ12\u003cbr\u003e\n• Maximum Units per GCS-1: 1 sensor per controller set\u003cbr\u003e\n• Application: Greenhouse \/ indoor cultivation climate monitoring\u003cbr\u003e\n• Photocell Function: Detects ambient light and determines day\/night mode\u003cbr\u003e\n• CO₂ Monitoring: Provides CO₂ PPM data to GCS-1 climate-control logic\u003cbr\u003e\n• Installation: Connects to the GCS-1 SENSORS port\u003cbr\u003e\n• Operating Temperature Range: 32–122°F (0–50°C)\u003cbr\u003e\n• Operating Humidity: 5–95% RH\u003cbr\u003e\n• Sensor Type: Replacement \/ standalone sensor\u003cbr\u003e\n• Included with GCS-1: One MBS-GH is included with a standard GCS-1 system\u003cbr\u003e\n• Replacement Use: For failed\/damaged sensors or an additional GCS-1 controller set\u003cbr\u003e\n• Compatibility: Green-X GCS-1 only\u003cbr\u003e\n• Hydro-X Compatibility: Not compatible with HCS-1, HCS-2 or HCS-3\u003cbr\u003e\n• Carbon-X Compatibility: Not compatible with Carbon-X CDA-1\u003cbr\u003e\n• Plug-and-Play: Replacement requires reconnecting the RJ12 cable; no controller reconfiguration is required\u003c\/p\u003e\n\n\n\u003cp\u003eKey Advantage: The MBS-GH combines four environmental inputs in one sensor—temperature, RH, CO₂ and day\/night detection—reducing cabling while providing the GCS-1 with the core environmental data needed for greenhouse automation.\u003c\/p\u003e","brand":"Hydro Supply Co.","offers":[{"title":"Default Title","offer_id":67610186088484,"sku":"TRLM-MBS-GH","price":199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0254\/3914\/1924\/files\/replacement-4-in-1-sensor-for-green-x-controller-mbs-gh.webp?v=1791317642","url":"https:\/\/www.growitdepot.com\/products\/trolmaster-replacement-4-in-1-sensor-for-green-x-controller","provider":"Grow It Depot","version":"1.0","type":"link"}
