This listing is the same part sold on its own, for replacement or as a spare. One head measures \u003cstrong\u003eair temperature, relative humidity and CO2\u003c\/strong\u003e, and a photocell tells the controller whether it is day or night. TrolMaster pairs an SHT31 temperature and humidity element with a separate NTC temperature sensor. CO2 readings are rated to \u003cstrong\u003e±70 ppm ±3%\u003c\/strong\u003e, and temperature to \u003cstrong\u003e±0.5°C\u003c\/strong\u003e. Humidity accuracy is ±3% RH. Data travels over \u003cstrong\u003eRS-485\u003c\/strong\u003e, which holds up well on the long cable runs common in greenhouses. It runs on 12V at 0.1A from the controller and uses less than 1W. A 4 ft RJ cable and a T-shaped splitter come in the box. TrolMaster backs the sensor with a 3-year warranty.\u003c\/p\u003e\u003ch2\u003ePlacing a Green-X 4-in-1 Sensor in the House\u003c\/h2\u003e\u003cp style=\"text-align: justify;\"\u003ePlug it into the GCS-1 sensor port, or into an SPH-1 splitter hub that feeds the controller. Let it hang freely at plant height, where the reading reflects what the crop actually feels. Keep it out of direct spray from foggers, misters and irrigation booms. Water or condensate on the housing will throw off readings and shorten sensor life. Clean it with a soft, dry cloth only, and never use solvents. If CO2 numbers look wrong, check that nothing is blocking the sensor opening first. Odd light readings can point to a dirty or shaded lens, so wipe it before recalibrating anything. Paired with the MBS-WS weather station, the controller can compare indoor and outdoor conditions on one screen. That comparison is what lets vent and curtain logic react to what is happening outside. The package measures 7.36 × 5.12 × 2.30 in and weighs 1.01 lbs per the tech sheet.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour Readings in One:\u003c\/strong\u003e Air temperature, humidity, CO2 and day\/night photocell from a single sensor head.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Accuracy:\u003c\/strong\u003e CO2 ±70 ppm ±3%, temperature ±0.5°C and humidity ±3% RH per TrolMaster.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRS-485 Signal:\u003c\/strong\u003e Stable data transmission over long greenhouse cable runs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow Power:\u003c\/strong\u003e Runs from the controller at 12V and draws under 1W.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-Year Warranty:\u003c\/strong\u003e TrolMaster covers the MBS-GH for three years.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background-color:#333; color:#fff;\"\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003ePart number\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eMBS-GH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eController\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eGreen-X GCS-1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eMeasurements\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eTemperature, relative humidity, CO2, light (day\/night)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eCO2 accuracy\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e±70 ppm ±3%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eTemperature accuracy\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e±0.5°C (0–50°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eHumidity accuracy\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e±3% RH (up to 90% RH)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eCommunication\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eRS-485\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eInput\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e12V, 0.1A; \u0026lt;1W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eOperating environment\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e32–122°F (0–50°C), ≤95% RH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003ePackage contents\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eMBS-GH sensor, 4 ft RJ cable, T-shaped splitter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003ePackage dimensions\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e7.36 × 5.12 × 2.30 in (187 × 130 × 58.5 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eGross weight\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1.01 lbs (0.46 kg) per tech sheet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eWarranty\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e3 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"TrolMaster","offers":[{"title":"Default Title","offer_id":50527963119830,"sku":"MBS-GH","price":189.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0723\/9450\/6454\/files\/trolmaster-mbs-gh-main-v1.webp?v=1790264277","url":"https:\/\/growershouse.com\/products\/trolmaster-replacement-4-in-1-sensor-for-green-x-controller-mbs-gh","provider":"GrowersHouse","version":"1.0","type":"link"}
