SensorPush HT.w for precise climate monitoring in humid growing environments

The SensorPush HT.w Sensor monitors temperature and relative humidity and is particularly well suited to grow tents, grow rooms, greenhouses and other environments where moisture levels may be elevated. Its water-resistant construction uses a protective sensor membrane and O-ring seals to provide protection from splashes and rain. Readings are taken every minute and transferred via Bluetooth to the SensorPush app, giving you a clear record of changing climate conditions.

Monitor temperature, humidity, dew point and VPD

The HT.w measures temperature and relative humidity with typical accuracy of ±0.2 °C and ±2% RH under the specified reference conditions. The app also displays calculated dew point and VPD values. For indoor growing, VPD can help you assess the relationship between temperature and humidity rather than relying on either measurement in isolation. You can find further climate monitoring equipment in the Measuring & dosing category.

45 days of measurements stored on the sensor

The sensor records new readings once every minute and retains 45 days of measurement history on board. When a compatible smartphone or tablet comes back within Bluetooth range, stored readings can be synchronised with the app and viewed as historical graphs. Adjustable alert ranges can also be configured in the app. Under ideal line-of-sight conditions, the wireless range is up to 100 m.

Water-resistant construction with optional remote access

A protective membrane over the humidity sensor and O-ring seals make the HT.w more suitable for splashes, rain and humid environments than an unsealed indoor sensor. For local operation, you only need Bluetooth Low Energy and the SensorPush app. If you want to access readings over the internet, the sensor can be paired with the optional SensorPush G1 WiFi Gateway. This makes the system suitable for remote monitoring of grow rooms and greenhouses as well as local climate checks.
