how to monitor temperature remotely without wifi

Wondering how to monitor temperature remotely without WiFi? It’s possible!

We understand that WiFi is one of the most frequently used technologies for remote control and receiving data on almost anything.

However, the wireless connection can’t be relied on, since the internet often drops and disconnects us from the application that we’re using.

To be able to monitor temperature and/or humidity remotely without using WiFi, we can either use the cellular internet on our phones or a digital temperature sensor. Those can deliver temperature information by SMS or phone calls, which does not require WiFi.

Let’s next unwrap the question that most of us stumble upon:

About Remote Temperature Monitoring Without Internet?

The straightforward answer is Yes, you can monitor the temperature, remotely without using WiFi or any sort of internet connection.

However, most of these setups involve purchases and we can hardly discover the necessary devices and electronic equipment at home.

The Solution?

If we’re not using WiFi, then surely we need to use another type of wireless connection, where for a greater distance, the only option available is radio frequency.

Another way to achieve the goal is by using cellular services (phone coverage) to receive temperature alerts!

We can see drastic changes in the temperature from an SMS message or simply by receiving an automated phone call.

Yes, this requires your phone to be in coverage to work, but yet we don’t need WiFi or any sort of internet to establish such a connection.

Let’s dig deeper!

How to Monitor Temperature Remotely Without WiFi?

There are two general methods that allow us to monitor temperature from a distance without being connected to the WiFi.

Moreover, we can even monitor the temperature in our home, without having any internet at all so let’s jump straight in!

Method #1 Remote Area Temperature Monitoring!

While the WiFi is hard to maintain intact, with the cellular connection on your mobile device you can overcome the hurdle when your router goes down.

There are numerous weather applications in the mobile application store that don’t require WiFi, only your GPS (location access), and any sort of internet.

In that regard, we can use our cellular data to track the temperature in our city/town remotely without WiFi.

Here is our best recommendation in regard to weather apps that you can use:

  • Weather & Radar
  • Weather Live
  • AccuWeather
  • The Weather Channel
  • Weather App Pro

All of them are free, but each and every smartphone, iOS or Android has its own dedicated weather app, pre-installed on the device.

Based on your preference you can download any of these apps or use the default weather app on your device.

Method #2 Monitor Home Temperature – No WiFi

Without using WiFi, it could be quite challenging to monitor the temperature inside our home remotely.

Yes, challenging but not impossible, and here we’ll review ALL possible methods of achieving this goal.

1. Digital Temperature Sensor!

One of the few ways that can allow you to monitor the temperature in your home or backyard without using WiFi is by purchasing a Digital Temperature Sensor.

Those devices can connect to WiFi, but they also provide other options to alert the user for temp changes!

Quick Fact: The sensor monitors temperatures between 4°F to 158°F (-20°C and 70°C).

The sensor can alert the user for temperature changes via SMS, Text Message, Voice Message, Cell Phone, Fax, Email, and even pager.

The wireless connection is only necessary for some of the destinations while others only require phone coverage.

2. Remote Weather Station

The Remote Weather Station is quite a complex device that doesn’t require WiFi and allows the user to monitor temperature from a distance.

This device is suitable for people that are caring for animals and require immediate alerts for changes in humidity and temperature.

  • The Remote Weather Station consists of two parts – Transmitter & Receiver!

The transmitter is powered by a power cable connected to the power and the receiver by a battery pack.

This way the receiver is mobile and hence can be allocated at a distance and send information through a Radiohead ASK library (Amplitude Shift Keying).

Here is everything required for the project:

  1. 2 x Atmega328 circuit board (nano).
  2. 1 x Transmitter & Receiver (315 Mhz).
  3. 1x Temperature and/or Humidity sensor.
  4. 4 x AA battery holder.
  5. 1 x Snappable Protoboard.

To accomplish the frequency transmission the antenna is used on “resonance” with or without a background infrared frequency.

When the boards are talking to each other, we can hook up the sensor to the transmitter, and soon after we’ll receive the temperature readings on the receiver.

Tip: If you’re not familiar with radio frequency, we strongly recommend searching for a technician to establish the setup for you!

3. Satellite Temperature Monitoring

The satellite weather station communication is only available for all-in-one services that provide everything all together.

There are many remote monitoring solutions even when you don’t have access to an internet connection, including cellular or satellite signal transmission.

The satellite does not measure the temperature and humidity directly and only measures radiances using wavelengths.

Hence, you’ll need a device that would perform the necessary mathematical equations and translate the readings into the temperature units that you need.

How do They Work?

These devices work by installing them into your home (desired location) and connecting your phone number.

From there on, you’ll be able to configure whether you want the notifications via SMS, a direct call on your mobile, via satellite signal (cellular), or no internet at all.

You don’t need a separate sensor since the component is inbuilt into the device.

However, these stations could be quite costly and such a purchase should be thoroughly considered before installation.

Good luck!

Quick Recap:

Now we’ve learned how to monitor temperature remotely without WiFi and apparently, using a digital sensor or radio frequency weather station is the only viable option.

This way we can receive temperature alerts by SMS or phone calls, which only require cellular reception!
