Temperature, humidity, light and CO2 monitoring for greenhouses
Fully waterproof front panel
Mobile APP and cloud platform for real-time data tracking, with breakpoint resume, no data loss
Automated scheduled reporting based on time frame
SMS, Email, APP push alerts for immediate action
Chargeable and replaceable high-capacity lithium battery, ensuring long service life

GSP100 series 4G/WiFi wireless real-time data loggers are designed for temperature, humidity, illumination and CO2 monitoring of greenhouses, laboratories and other applications. The wireless real-time data loggers transfer data to Freshliance Cloud via WiFi or 4G network, enabling automated data tracking and seamless documentation in real time with the mobile APP and cloud platform. The real-time data monitors help growers understand the greenhouse environment and plant growth and also help users in other applications to get peace of mind in cold chain management.
Illumination data graphing and export
Beyond tracking temperature and humidity, GSP100 series environmental real-time data recorders also feature integrated illumination and CO2 monitoring, making them an ideal solution for greenhouses, laboratories, and other applications. All data are accessible and exported in real time via the mobile APP and cloud platform, with automated graphing and analysis to enable users to get the trends and make swift actions.
Fully waterproof front panel
Greenhouses often have high humidity levels and frequent condensation. The fully waterproof front panel makes the logger resistant to water splashes and condensation whether from automated irrigation systems, manual watering or wet hands, and resistant to airborne dust and dirt. The waterproof front panel ensures the flexibility in device placement and the longer operational lifespan, with continuous, uninterrupted monitoring.
Mobile APP and cloud platform for real-time data tracking and processing, API service optional
Both real-time and history data are globally accessible via the mobile APP and cloud platform, requiring no frequent on-site check and transforming the raw data into actionable insight for decision-making. These real-time data loggers also support breakpoint resume to ensure no data loss in case of network failure. The optional API service allows users to effortlessly pull cloud-based data directly into their own websites or dashboards for data analysis and centralized management, etc.
Automatically send reports to emails as scheduled
The cloud platform supports scheduled reporting, which allows users to automatically receive the data reports of one or multiple devices via emails based on the preset report format and time frame—daily, weekly, or monthly. It avoids the omission or delay of reports due to staff overload, absence or negligence, and ensures the continuity and integrity of the data.
Multiple alerts via SMS, Email, APP push
To ensure high reliability of the real-time monitoring, we also provide real-time alerts via SMS, Email and APP push. The multi-channel alerts ensure users are informed immediately without coming to the site and take precautions to avoid losses.
Multi-level administration access optional
For data privacy and centralized management of devices, organizations can apply for the multi-level administration access to the cloud platform, assigning different roles and permissions to different members in the organizations and ensuring audit compliance.
Rechargeable and replaceable battery
In addition to the USB Type-C interface for main power supply, GSP100 series real-time temperature data logger also has a rechargeable and replaceable lithium battery as the backup power. The battery can work for up to 60 days (uploading interval: 15min), significantly ensuring uninterrupted data monitoring during mains power failure. The replaceable battery also offers higher flexibility in battery maintenance.
