A SensorPush HTP.xw can help you build a time-stamped record of environmental conditions during a ghost hunt. Use it to compare changes at a fixed location with your notes about doors, vents, weather and people’s movements. A graph can document a change; it cannot tell you that the cause is paranormal.
This guide explains a practical logging method using documented product capabilities. It is not a hands-on review or a claim that HauntGears tested this sensor.

What the SensorPush HTP.xw records
The HTP.xw measures air temperature, relative humidity and barometric pressure. Its log can be reviewed in the SensorPush mobile app. Unlike the HT1 and HT.w models, it includes pressure measurement. Check the model name rather than assuming all SensorPush sensors have the same capabilities.
| Measurement | Useful context to note | What it does not establish |
|---|---|---|
| Air temperature | Sensor position, nearby vents, open doors and heating changes. | The temperature of every surface or every part of the room. |
| Relative humidity | Changes in ventilation, moisture sources and occupancy. | The identity or cause of a reported presence. |
| Barometric pressure | The wider weather context and the timing of observations. | A paranormal explanation for an unusual experience. |
Plan your log before you enter the room
Begin with permission to investigate and record at the location. Decide what question the log should help answer: for example, whether a reported temperature change coincided with a door opening. A specific question is more useful than searching afterward for any unusual-looking line.
Choose a fixed placement you can describe precisely, such as a shelf away from an open window. Record the height, room and nearby equipment. Avoid holding the sensor in your hand while comparing different periods. If you move it, mark that change in your notes so a new position is not mistaken for a change at the original position.
A simple recording workflow
- Check setup at home. Install the current SensorPush app on a compatible phone, pair the sensor and confirm you can retrieve a log before relying on it at a location.
- Align your clocks. Check your phone, camera and written-log times. Note any difference rather than assuming every device uses the same time.
- Record a baseline. Observe the room before the main session and write down ordinary conditions, including ventilation, lighting equipment and people present. Keep the placement consistent.
- Log interventions. Note doors opening, equipment being moved, people approaching the sensor and heating or cooling switching on. Describe what happened without first assigning a cause.
- Sync and preserve. Bring your phone within Bluetooth range, confirm the readings transferred, and retain an export with your original notes. Keep an unchanged copy before annotating graphs.
- Compare fairly. Look at quiet periods as well as the moment someone reported an experience. Ask whether the same pattern occurs without that report.

Bluetooth, remote access and sampling limits
The sensor records once per minute and keeps about 30 days of readings internally. Sync regularly rather than treating that storage as a permanent archive. A brief event between samples may not appear in the log.
A phone nearby can retrieve readings over Bluetooth. Internet access from elsewhere requires the optional SensorPush G1 WiFi Gateway, sold separately, plus a suitable connection at the location. Buying the sensor alone does not create a direct WiFi monitoring system. Walls and other obstacles can reduce wireless reach, so test coverage where you plan to use it.
Is it the right instrument for your question?
Choose a logger when you need a record over time. If you need to see the pattern of surface temperatures across a scene, a thermal camera serves a different purpose. If you need an immediate local reading on a visible screen, compare a display-equipped instrument. Avoid expecting one tool to answer every environmental question.
The HTP.xw is water resistant, but that does not mean it should be submerged. Use it within the manufacturer’s instructions. Check the current app requirements and confirm the selected blue HTP.xw, ASIN B08PKVRJJX, before ordering.

Frequently asked questions
Can it measure a “cold spot” instantly?
It logs air conditions at its own position. It does not scan a room, and one-minute sampling is not a continuous record of every instant. Placement changes and the sensor’s response to new conditions matter when interpreting a graph.
Do I need the G1 gateway?
Not for nearby Bluetooth retrieval with a compatible mobile device. You need the separately sold gateway for the manufacturer’s remote internet-monitoring setup.
Does it detect ghosts or prove a haunting?
No. It measures ordinary physical conditions. A change can have multiple explanations, and a coincidence between a reading and a report does not establish causation.
Can I compare two rooms?
For simultaneous readings, use separate sensors and document each placement. Moving one sensor between rooms also changes the time and surroundings, so it is a different comparison.
