Additional info / Buyers Guide

We all appreciate the security of knowing our valuables, our property, our pets or our business are protected and secure. Nothing is worse than coming home to a broken pipe, or worse, an animal in distress.

But if you’re not home or away for an extended period, nature, equipment failure or accidents can create havoc for the things you care about. Nothing takes the place of being able to access vital data about your home or business when you can’t be there.

Here are factors to consider when shopping for your remote sensing monitor system.

Access to Data and Alerts

The models listed here all send critical alert data to your connected web device – smartphone, tablet or computer. Most use a 433mhz remote temperature sensor system. Some send regular readings continuously like the SensorPush Wireless Thermometer / Hygrometer, which takes readings every minute, logging them with a time stamp. All the units instantly send alerts should something go awry.

Unlike the others, the MarCELL Cellular Connected Monitoring System sends data using a cellular system, not relying on local WI-Fi. Some units like the AVTECH send SMS/text alerts, and the ConnectSense CS-TH can even alert you on Twitter. The SensorPush comes with a free app for your smartphone iOS 8+ or Android 4.3+.

Types of Data Collected

All the units have the capability to collect temperature and humidity data. Also, some like the ConnectSense monitor for water leaks, motion, security door/window, dry contacts and even light. Some models allow for the addition of extra sensors such as the La Cross Alerts Mobile, and the AcuRite 01166M 3-Sensor Monitoring System can accommodate as many as ten extra sensors.

Data Visualization

The SensorPush can export its data to .csv files so you can import the information into an Excel spreadsheet for further study and evaluation. Other models like the La Cross Alerts Mobile and the Temp° Stick collect unlimited historical data. Also, the AcuRite 01166M creates charts and graphs of all received data. The [email protected] USB Edition exports its data into custom applications for further analysis.

Power Up

Some models such as the Temp° Stick run on battery power. Two exceptions – the [email protected] USB Edition plugs into your computer’s USB port and uses the computer’s power – no other power source is needed. And, the AVETECH Room Alert 3E features a power over Ethernet (PoE).

Cost and Warranties

Our most economical model, the La Crosse Alerts Mobile 926-25101 GP will only set you back $29. On the other end of the spectrum, the MarCELL Cellular Monitoring System comes to $179 but includes features such as an internal modem and multiple zone sensors which have a range of up to 200 feet. Warranties also vary with the SensorPush offering a no questions asked two-month warranty, to the AVTECH’s full one year warranty.

Conclusion

Just a few years ago it would have been impossible or extremely costly to monitor conditions like these in your home or business. Now in 2017, thanks to the web, WI-FI, cellular networks and the internet of everything, you can be your own monitoring station, knowing instantly if something has gone wrong, even if you are thousands of miles away. It’s a new networking age helping to ensure peace of mind and security for the important things, people, and valuables in your life.
