Choosing between a pressure sensor and a wireless temperature sensor isn't about picking a better product - it's about what your machine actually needs to measure. The Monnit Industrial Wireless Temperature Sensor sends temperature data to the Monnit system using a pre-installed battery and a 900 MHz antenna. The Honeywell 89028 4 Industrial Pressure Sensor offers a straightforward pressure measurement part at a much lower price. This head-to-head breaks down the two so you can match the right sensor to your sensors, encoders, and machine safety setup.
Quick Verdict
Go with the Monnit wireless temperature sensor if your job is remote temperature monitoring and you want a self-contained unit with mounting hardware and battery included. Choose the Honeywell pressure sensor if you need an industrial pressure sensor and don't need wireless.
Comparison at a Glance
| Product | Price | Sensor type | Key details | Best for |
|---|---|---|---|---|
| Monnit MNS2-9-IN-TS-ST-L03 | $100.00 | Wireless temperature | 3-foot lead, SMA antenna, pre-installed 3V battery, mounting hardware | Remote temperature monitoring |
| Honeywell 89028 4 / 103716 | $23.95 | Industrial pressure | Model 103716, MPN 8902842131, new condition | Direct pressure measurement |
Where Each Product Wins
- Monnit wins if you want a wireless temperature sensor that is ready to mount and run on battery power. The included SMA antenna and 900 MHz operation are built for the Monnit system.
- Honeywell wins if you want an industrial pressure sensor and pressure is the only variable you need to track.
Product Notes
Monnit Industrial Wireless Temperature Sensor MNS2-9-IN-TS-ST-L03

The Monnit Industrial Wireless Temperature Sensor (MNS2-9-IN-TS-ST-L03) is the option to pick when running wires to a sensor is impractical. It comes with an SMA antenna for 900 MHz USA operation, a 3-foot temperature lead, mounting hardware, and a pre-installed 3V industrial battery, so it can go into place and start reporting without a separate power run. It is in new open-box condition. Choose it if your priority is a self-contained temperature monitoring setup that works with the Monnit system. The limitation is that its job is temperature monitoring; for pressure, you would need a different sensor.
Honeywell 89028 4 Industrial Pressure Sensor 103716 8902842131 NEW

The Honeywell 89028 4 Industrial Pressure Sensor (model 103716, MPN 8902842131) is the straightforward industrial pressure sensor for a pressure-only job. It is new. The part number and model identify it clearly as a Honeywell unit. If your project is pressure monitoring and you don't need wireless capability, this sensor covers that need. The trade-off is that it is specifically a pressure sensor - if your process also needs temperature, you would pair it with a separate sensor. For a pressure-only job, that's often exactly what you want. For a sensors, encoders, and machine safety environment that needs both, you'd combine it with a temperature solution.
Final Choice by Use Case
- Choose the Monnit Industrial Wireless Temperature Sensor if you need to monitor temperature in a location where running wires is difficult. Its battery, antenna, and mounting hardware are all included, and the 3-foot temperature lead gives you placement flexibility.
- Choose the Honeywell 89028 4 Industrial Pressure Sensor if your priority is a pressure sensor for an industrial application. The model 103716 and MPN 8902842131 give you the part identifiers, and the new condition makes it a straightforward option when pressure is the only variable you need to track.
