SensorPush HT.w - Water-Resistant | Humidity / Temperature / Dewpoint / VPD Bluetooth Sensor

A: SensorPush sensors record data every minute. Currently, the sample rate cannot be adjusted. However, the CSV export functionality in our applications allows data to be exported at reduced intervals (e.g., every 15 minutes or hourly) to help keep data files manageable if the extra detail is not required. Learn more about exporting data to CSV files.

The current conditions are broadcasted for nearby mobile devices and SensorPush G1 WiFi Gateways to see immediately. Conditions are also logged on the device, allowing you to download a full history later. The amount of storage depends on the sensor model, with current models ranging from 20 to 45 days.

A: Both the sensor and the app store data. The sensor automatically maintains a backup of the most recent 20 days of readings. If you are away from the sensor, it will continue to record the conditions. When the sensor reaches 20 days, it starts to overwrite the oldest data points.

Once the data is picked up by the app, it is stored indefinitely on your mobile device. Similarly, when a SensorPush G1 Gateway is used in conjunction with the sensor, the data is stored indefinitely in the SensorPush cloud.

A: Absolutely! Many individuals and businesses use SensorPush to monitor their refrigerators, freezers, or even commercial walk-in coolers. However, there are some important considerations:

• Signal Strength/Range: Signal strength will be reduced because the signal has to travel through the walls of the equipment. In a normal refrigerator or freezer, you'll likely get a good signal in the same room or in adjacent rooms, but the range won't be as long as it would be if the sensor were outside. When placing a G1 WiFi Gateway, keep it relatively close to the refrigeration equipment. If you need it to be farther away, a little trial and error may be required to ensure a reliable connection.
• Water Absorption: Water effectively absorbs Bluetooth signals, and since most food products contain a high percentage of water, this can affect the usable range. The range can vary significantly based on how the sensor is placed within the equipment.
• Battery Efficiency: Batteries are less efficient at cold temperatures. In a refrigerator, this effect is minor, but in very cold freezers, you might need to change the battery more often—possibly every 6-12 months instead of the usual 2+ year interval.

For best results in sensitive applications, combining the sensors with a G1 WiFi Gateway is recommended. Since the range is reduced inside refrigeration equipment, the best way to ensure you are always up to date and alerted when issues arise is by using the SensorPush Cloud and the G1 WiFi Gateway.

A: Yes, SensorPush sensors can perform well outdoors, provided they are protected from direct sunlight and precipitation.

While the sensors are not designed to be submersible and thus not classified as waterproof, the HT.w and HTP.xw models are water-resistant. They feature o-ring seals and protective sensor membranes, making them more robust and suitable for outdoor use.

Many users have had good results with the HT1 sensor when it is placed under the eave of a roof or in similarly protected outdoor conditions. Since the HT1 has an open sensor hole, it is advisable to mount the sensor with this hole facing downward to reduce the likelihood of water or debris entering the device.

Regardless of the model, you should protect your sensor from direct sunlight. Solar radiation can heat the sensor's casing, skewing the temperature and humidity readings. For optimal accuracy, choose a mounting location that shields the sensor from direct sunlight and precipitation while allowing good airflow. Mounting the sensor under an eave generally works well. Additionally, there are specially designed solar radiation shields available for such applications.
