The Reason Why Greenhouses Choose SenseCAP Combo 5-in-1 Sensor
An Expandable 5-in-1 Sensor Solution for Precision Monitoring and Remote Management
The SenseCAP Combo 5-in-1 Sensor for greenhouse monitoring helps growers track the environmental changes behind daily decisions. How do temperature and CO₂ levels shift after vents open in the morning? How much does light intensity fall beneath a shade screen? How long does high humidity persist overnight? Recording these changes over time provides useful context.
SenseCAP Combo 5-in-1 Sensor with 4G brings air temperature, relative humidity, CO₂, light intensity, and atmospheric pressure monitoring into one device. It also combines solar charging, cellular connectivity, local data caching, and RS485 expansion.
Together, these features make it easier to build a continuous record of greenhouse conditions. As monitoring needs grow, compatible root-zone or leaf sensors can extend coverage within the same system.
Five Environmental Parameters in One Device
Greenhouse management requires understanding how environmental conditions interact. Opening vents can change temperature, humidity, and CO₂ levels simultaneously, while changes in light intensity after shading are best understood alongside temperature readings.
By measuring five parameters in a single node, SenseCAP Combo 5-in-1 Sensor helps growers review environmental changes in the same growing area. It also reduces the work involved in installing, powering, and maintaining multiple standalone instruments.
High-Accuracy Environmental Monitoring
SenseCAP Combo 5-in-1 Sensor delivers high-accuracy environmental monitoring to help growers make confident greenhouse management decisions. It measures air temperature with ±0.2°C accuracy, relative humidity with ±2% RH accuracy, light intensity with ±5% accuracy, and atmospheric pressure with 1 hPa accuracy. CO₂ measurement accuracy is ±(50 ppm + 3% of the reading) from 0–5,000 ppm and ±5% from 5,000–10,000 ppm, while calculated dew point offers ±2°C accuracy for additional insight into condensation risk.

The Louvered Enclosure Combines UV Resistance with Natural Airflow
Reliable temperature measurement requires protection from direct solar radiation and accumulated heat. SenseCAP Combo 5-in-1 Sensor uses a louvered structure to shade the temperature and humidity sensing area while maintaining natural airflow. As a result, the sensor can respond more effectively to changes in the surrounding greenhouse environment.
The enclosure is made of PC/ASA and carries an F1 UV resistance rating. This material helps the housing withstand prolonged ultraviolet exposure and reduces the risk of premature aging during long-term deployment.
In addition, the open lower structure supports passive ventilation and heat dissipation. Together with the top-mounted solar panel and separated sensing areas, the design combines environmental monitoring, solar energy harvesting, and outdoor durability in one compact device.
Ventilated Design Reduces Heat Buildup and Condensation Impact
The SenseCAP Combo 5-in-1 Sensor with 4G is designed for greenhouse conditions, including daytime heat, high humidity, and day-to-night temperature changes. Its multi-layer louvered housing and vented bottom provide protective coverage while keeping airflow paths open.
The louvers help shield the sensing area from direct sunlight. Gaps between the louvers and openings in the bottom sensor cover allow ambient air to circulate around the sensors. This helps reduce trapped heat and its influence on temperature and humidity readings.
The open design also supports moisture dispersal, helping limit localized moisture retention and reduce the potential impact of condensation. A sealed electronics compartment and PCBA-level waterproof treatment add moisture protection for key circuits. Together, these features balance airflow around the sensors with protection for the electronics, supporting continuous greenhouse monitoring.
Proven Durability from Three-Axis Vibration to Thermal Shock Testing
SenseCAP Combo 5-in-1 Sensor is designed for mechanical stability and environmental resilience. It operated normally for 48 hours at 50°C and 98% RH, as well as for 48 hours at −20°C. Additionally, it completed 24 thermal shock cycles between −20°C and 60°C, with each temperature maintained for 60 minutes and transition times kept within five minutes. Three-axis vibration testing included a resonance search at 4–100 Hz and 1g, followed by a one-hour dwell test in each direction; afterward, the device remained functional, with no cracking, deformation, or loose screws observed. Moreover, following 24 hours of salt spray testing with a 5% sodium chloride solution at 35±2°C and 48 hours of drying, its appearance and functionality remained normal, providing concrete evidence of its durable design.
Connecting Air and Root-Zone Monitoring with Solar-Assisted Power and Sensor Expansion
From greenhouse air to the crop root zone, the SenseCAP Combo 5-in-1 Sensor for greenhouse monitoring connects air and root-zone measurements in one system. Built-in sensors monitor temperature, humidity, CO₂, light, and atmospheric pressure. A Modbus-RTU RS485 interface supports up to 10 compatible external sensors through a splitter, allowing you to add soil or substrate monitoring as needed. An integrated solar panel rated at up to 1W works with a 5200mAh rechargeable battery to replenish power when sunlight is available. This reduces reliance on fixed power wiring and offers greater installation flexibility. With 5V and 12V outputs for external sensors, you can expand your setup as your needs grow. Power requirements depend on local sunlight, sensor consumption, and sampling frequency. When connecting 12V external sensors, the SenseCAP Combo 5-in-1 Sensor itself must be powered by an external DC power supply. Product Specifications · Connection Guide
Direct 4G Connectivity and Offline Caching Support Reliable Remote Monitoring
SenseCAP Combo 5-in-1 Sensor uploads environmental data directly to the cloud via 4G Cat.1 and MQTT, without an additional gateway or on-site Wi-Fi. Multiple frequency bands and configurable APN settings support deployment across local carrier networks. When connectivity weakens or drops, the device can cache up to 500,000 data records locally. Once the connection returns, it automatically uploads the cached records to help reduce data gaps. Meanwhile, local export makes historical data easier to back up and analyze. For flexible integration, SenseCAP Combo 5-in-1 Sensor supports both the SenseCAP platform and custom third-party MQTT servers. The platform also provides HTTP, MQTT, and WebSocket APIs to connect monitoring data with existing management systems. Users can view data and device status remotely through the SenseCAP Portal or the SenseCraft App. In addition, OTA firmware updates reduce on-site maintenance, making distributed greenhouse monitoring easier to manage.
