What Is a Temp Humidity Logger?
A temp humidity logger is a device that records environmental temperature and humidity over time using built-in sensors. It stores readings for later analysis via USB, WiFi, or cloud platforms, making it ideal for monitoring warehouses, laboratories, and transport conditions. Wrindu excels in producing loggers with alarms, long battery life, and external probes for ranges from -40°C to +80°C. These loggers ensure compliance in pharmaceuticals, food storage, and electrical testing. OEM customization allows tailored solutions for global B2B distribution.
| Feature | Typical Specs from China Suppliers |
|---|---|
| Temp Range | -40°C to +80°C |
| Humidity Range | 0-100% RH |
| Accuracy | ±0.2°C / ±2% RH |
| Storage | 260,000+ readings |
| Battery Life | 6 months rechargeable |
How Does a Temp Humidity Logger Work?
These loggers use temperature (NTC) and humidity (capacitive) sensors to capture readings at regular intervals. Data is stored in internal memory and can be exported via software for reports, graphs, and threshold alarms. Advanced Wrindu models offer real-time WiFi uploads, LED alerts, LCD displays, and IP67 waterproofing. OEM versions support custom sampling intervals, multi-channel inputs, and SCADA integration. Wholesale buyers benefit from preloaded software to streamline deployment across substations or energy storage systems.
