⚠️ TSTH1-B is transitioning to the next-generation product: T-one. T-one offers improved performance, longer battery life, and ongoing production support.
TSTH1-B
BLE 5.0 Temperature & Humidity Sensor
It collects the temperature and humidity of the environment and transmits the data via BLE to trackers or BLE hub, then transmitted to server finally. Designed for the demands of the environmental monitoring industry to resolve losses caused by unexpected and unfriendly temperature and humidity changes.
Features
BLE 5.0
It can be used for data broadcasting and wireless configuration
High accuracy
Accuracy of ± 0.2 ℃ for temp, and 2% RH for humi
Frequent data broadcasting
Broadcasting data every 60s by default (configurable)

Product Status
TSTH1-B will be a legacy model. For new projects, we recommend T-one, which is fully compatible and actively produced.
| Feature | TSTH1-B | T-one (with Probe) |
|---|---|---|
| Sensor type | Internal temperature sensor | External temperature probe |
| Temperature detection | Ambient / limited range | Wider temperature differential detection |
| Measurement position | Fixed (device body) | Flexible, probe-based placement |
| Use case suitability | Standard temperature monitoring | High temperature variation environments |
| Deployment flexibility | Limited | High – adaptable to complex scenarios |
| Recommended for | Existing deployments | New projects & demanding applications |
Unlike TSTH1-B, which relies on an internal sensor, T-one supports an external temperature probe, allowing measurements in locations where temperature differences are more extreme or where ambient readings are not sufficient.
This makes T-one better suited for applications requiring accurate monitoring across wider temperature gradients.
