The best wireless temperature sensors of 2020

A wireless and WiFi temperature sensor is necessary for homes in countries with four seasons. Temperatures change constantly because of Global Warming.

Do you remember some days where the temperature in your house is warm in the morning and cold at night?

You can feel it physically, but without a sensor or a thermometer, it’s hard to tell the exact temperature. Also, when you’re outside most of the time, it’s difficult to monitor the temperature in your home. That’s why a wireless or a WiFi temperature sensor is a great addition to any house, especially for smart homes.

What is a WiFi Temperature Sensor?

A wireless or WiFi temperature sensor is a device that records and keeps track of temperature changes in the area where you install it. It often sends real-time data to your smartphone.

Using this helps you to monitor the temperature inside and outside your home remotely. It works hand-in-hand with smart thermostats. After the sensor gathers data, you can adjust the thermostat in your home depending on the current temperature and humidity.


The Advantages of WiFi Temperature Sensor

In the past, you would need a physical thermometer to measure the temperature in a certain area. For humidity, you’d have to buy a separate hygrometer.

Buying both of these devices can cost a lot of money, and high-quality ones with accurate readings are expensive.

Today, you can buy a temperature sensor that you can connect to your phone using a WiFi connection. Most of these sensors today can also record humidity making it a high-value product.

Another advantage of these temperature sensors is that you can connect it to smart home devices. This enables the other smart gadgets to function according to the readings from the sensors.

It also helps you save on additional repair costs in your house. Fluctuating temperature and humidity changes can damage wooden houses. If you have a sensor and you find patterns in temperature changes, you can adjust the thermostat accordingly to avoid sudden temperature change in your house.

What We Liked

We like how the manufacturer gives you total control over the desired data – you can set your own hi-lo triggers. Choose between Celsius and Fahrenheit or customize how you want the alerts to be.

You can program and set a temperature limit. Once that is exceeded, you will receive messages or emails to as many accounts as you like.

Also, you can log into your account and specify how frequently you want the device to report data — keeping the battery life into account.

Its battery life is excellent, which also depends on how often you pull stored data. The sensor can last more than a year if you use high-quality batteries. Because of this, you won’t have to worry about changing them often.

What We Didn’t Like

A downside to the Temp Stick is that it can’t show you real-time data — it has a limit of 5-minute up to hourly time intervals. We think that Ideal Sciences could’ve added this feature given its price tag.

And one more thing. We feel that additional sensors that you could monitor using one app will be a useful improvement.

What We Didn’t Like

What we’d improve in the SensorPush is the Wi-Fi connection. There is an option for this, but it will cost extra.

And as mentioned above, the range of the device is outstanding. However, any obstacles between the sensor and your phone reduce the signal quality.

You’ll also need to calibrate the sensor from time to time because there can be inconsistencies in the stored data — a 5-degree difference between 2 devices placed in the same room.

What We Didn’t Like

We think it would have been great if the LCD screen has back-lighting so you can read it even in the dark.

You need lithium batteries for low temperatures because alkaline ones seem to malfunction. We find this as a slight drawback.

This is a disclaimer that comes with the instruction manual. Once this problem arises, you have to bring the unit in, re-insert the batteries and calibrate it with the other unit.

For what it offers, we think this is an excellent device for simple temperature measurements for an average user.

What Other People Ask

Can a smartphone be a thermometer?

Yes, it can either use its built-in thermal sensors or with the use of appropriate apps.

What is the difference between active and passive sensors?

Passive sensors only detect and respond to some type of input they receive. Active sensors usually require an external power source to operate.
In the context of remote sensing, the active sensors are devices that transmit a signal — light wavelength or electrons — that bounces off the target with gathered data upon reflection.

How do you calibrate a sensor?

There is more than one method to do this:
1. Calibrating the electronics – you have to use a temperature simulator. You input the temperature and it returns an appropriate resistance or voltage.
2. Calibrating the sensors and the electronics – you will need a dry-well to place the probe in, then compare the measurement with its built-in thermometer.
3. Calibrating the sensors and the electronics with a reference thermometer – you put the thermometer in a dry-well, but the measurement is compared with another thermometer placed in an adjacent hole for higher accuracy.

    1. Hi Bob, the AcuRite 00782A2 Wireless Indoor/Outdoor Thermometer is not Wi-Fi enabled. The wireless part that the product refers to is the wireless connectivity between the unit sensor and the unit display. The unit sensor will be placed outside of your home while the display unit will be inside.

  2. Hello, I am a condo townhome owner living on water with a crawlspace containing plumbing (water and sewage lines). We have heaters designed to come on at 7 degrees celcius to keep plumbing from freezing. I want to put a wifi-enabled sensor in the crawlspace to measure/monitor temps all winter long. It gets pretty cold up here in northern Ontario. Which temp sensor would you recommend?
