Honor Play 4 Infrared Thermometer Camera?
No, the Honor Play 4 does not have an infrared camera that can take your temperature. The Honor Play 4, released in 2020, is a budget smartphone with a standard camera setup, and it does not include any thermal or temperature-sensing hardware. The confusion likely arises from the Honor Play 4 Pro, which does feature an infrared temperature sensor, but that is a different model with different capabilities.
Background: The Honor Play 4 Series
The Honor Play 4 series includes several models: the Honor Play 4, Play 4 Pro, and Play 4T. These phones were launched in mid-2020, primarily targeting the mid-range and budget segments. The standard Honor Play 4 features a 6.81-inch LCD display, a Kirin 990 chipset (in some variants) or MediaTek Dimensity 800, and a triple rear camera system. The Play 4 Pro, on the other hand, is a more premium device with a dual punch-hole display, a Kirin 990 5G processor, and an additional infrared temperature sensor on the back.
What the Infrared Sensor Does on the Play 4 Pro
On the Honor Play 4 Pro, the infrared sensor is not a camera in the traditional sense. It is a dedicated temperature sensor that measures the infrared radiation emitted by an object. The sensor is placed on the back of the phone, next to the camera module. It works by detecting the thermal energy and converting it into a temperature reading, which is displayed in the phone’s built-in Health app or a dedicated utility. The sensor can measure the temperature of objects, surfaces, and even the user’s forehead (though not for medical diagnosis).
How the Temperature Measurement Works
The infrared temperature sensor on the Play 4 Pro uses the principle of thermopile detection. A thermopile is a device that converts thermal energy into an electrical voltage. When you point the sensor at an object, the infrared radiation from that object heats the thermopile, generating a voltage that is proportional to the temperature. The phone’s software then converts this voltage into a temperature reading, typically displayed in degrees Celsius or Fahrenheit. The sensor has a stated accuracy of ±0.2°C when measuring temperatures between 35°C and 39°C, which is suitable for surface temperature checks.
Common Misconceptions and Confusion
Many people confuse the Honor Play 4 with the Play 4 Pro because of the similar naming. Some online listings or articles may incorrectly state that the standard Play 4 has the infrared sensor. Additionally, some users might mistake the laser autofocus module on the Play 4 for an infrared sensor. The laser autofocus helps the camera focus quickly but does not measure temperature. It’s important to check the exact model number and specifications before purchasing if you specifically need the temperature sensor feature.
How to Check if Your Phone Has the Sensor
If you own an Honor Play 4 series phone and want to know if it has the infrared temperature sensor, follow these steps:
- Look for a small, circular opening on the back of the phone, separate from the camera lenses and flash. On the Play 4 Pro, this is located near the camera module.
- Check the phone’s specifications in the Settings app under “About phone” or on the official Honor website.
- Look for a pre-installed app called “Temperature” or “Smart Remote” that uses the sensor. If the app is missing, the phone likely does not have the sensor.
- Search online for your exact model number (e.g., “Honor Play 4 Pro” vs. “Honor Play 4”) to confirm its features.
Alternatives for Temperature Measurement
If you need a phone with an infrared temperature sensor, the Honor Play 4 Pro is one of the few models that includes it. Other options include the Honor 30 Pro+ (which has a similar sensor) and some rugged phones like the Blackview BV9900 Pro. However, if you don’t need this feature, the standard Honor Play 4 is still a capable device for everyday use. For measuring body temperature, dedicated medical thermometers are more accurate and recommended.
Safety and Accuracy Considerations
The infrared sensor on the Play 4 Pro is not a medical device and should not be used for diagnosing illness. It measures surface temperature, which can be affected by environmental factors like ambient temperature, humidity, and the distance between the sensor and the object. For accurate readings, the sensor should be held close to the target (within a few centimeters) and the target should be at a stable temperature. The sensor is designed for measuring objects, not for clinical use. Always follow the manufacturer’s guidelines and consult a healthcare professional for medical concerns.
Frequently Asked Questions
Can I measure my body temperature with the Honor Play 4 Pro?
Yes, you can point the sensor at your forehead to get a surface temperature reading, but it is not intended for medical diagnosis. The reading may be affected by sweat, ambient temperature, and distance. For accurate body temperature, use a medical thermometer.
Is the infrared sensor the same as a thermal camera?
No. A thermal camera creates a visual image based on heat distribution, while the sensor on the Play 4 Pro only measures the temperature at a single point. It cannot produce a thermal image.
Does the Honor Play 4 have a temperature sensor?
No, the standard Honor Play 4 does not have an infrared temperature sensor. Only the Honor Play 4 Pro includes this feature.
Can I use the sensor to measure the temperature of liquids?
Yes, you can measure the surface temperature of liquids, but the sensor should not be submerged. The reading may be inaccurate if the liquid is steaming or if the sensor is too far away.
Why did Honor include a temperature sensor on a phone?
It was likely added as a utility feature, especially during the COVID-19 pandemic, to allow quick temperature checks of objects and surfaces. It also serves as a unique selling point for the device.
