Beware of Defective, Wrongly Manufactured IR Thermometers

Defective IR Thermometer

There is a lot of demand for medical supplies and equipment due to COVID-19. IR Thermometers are used to check the temperature of people before entering a building for instance and are also in short supply. So factories are frantically mass-producing everything they can from face masks to IR thermometers, and it looks like some may forgo quality control.  The latter are very hard to find in Thailand, but one person managed to purchase an IR thermometer online and decided to open it… [Update April 16th 2020: The Facebook video has been taken, but still available on Youtube] This Heaco MDI908 medical thermometer’s infrared board is not connected to the mainboard, so it “works” even without the IR sensor… This takes “non-contact infrared thermometer” to a whole new level 🙂 I can see Kaidee (Thailand’s eBay) had some listed a few days, but the pages have since then been taken down. What I believe to be the company’s website (heaco …

This Non-Invasive AI Temperature Screening System Checks Multiple Persons On-the-Fly

Remote AI Temperature Monitoring System

Yesterday, I had to go to the bank with the branch located in a building where they closed all doors except one in order to make sure all people were wearing masks, check their temperature, and let them wash hands with alcohol hand gel. Those are good preventive measures to slow the spread of SARS-CoV-2 virus, but in case many people visit a location that’s also time-consuming. I’ve just come across a system that should speed up the process, as it can check forehead temperature of people as they walk by, using a camera and artificial intelligence for face detection, and an IR camera/thermometer to report temperature. Remote AI temperature screening system specifications: SoC/Memory/Storage – Don’t know, but I would not be surprised if it was based on RK3399 since Rockchip often promotes AI use cases for this processor. External Storage – MicroSD card, USB drive Video Output- HDMI 2.0 output Connectivity – Ethernet & WiFi with external antenna Camera …

PUCK 2 Bluetooth to IR Bridge Allows you to Control Appliances from your Android or iOS Phone

PUCK v2

We’ve already seen there are several solutions to control IR appliances such as air conditioners or (dumb) televisions via your smartphone thanks to solutions such as ZaZa Remote  that adds an IR transmitter to your 3.5mm audio jack or more recently via your USB-C port. If you don’t quite like having extra hardware connected to your smartphone WiFi to Infrared bridges such as the compact and omnidirectional Broadlink RM Mini 3 are cost-effective solutions, although you’d need one in every room where you wish to control appliances. I’ve recently noticed an even smaller “smartphone to IR” solution with PUCK v2 Bluetooth to IR bridge. The full technical details about PUCK 2 have not been made available, but we do know it’s a Bluetooth 4.2 to infrared remote bridge that transforms any iOS or Android device into a remote. The infrared LED has a range of about 4.5 meters, while Bluetooth works up to 30 meters. All you have to do …

Use your Smartphone as an IR Remote Control with ROCK USB Type C IR Remote Control Transmitter

A few years ago, I wrote about ZazaRemote transforming your smartphone into a universal IR remote control. ZazaRemote is a hardware and software solution that combines infrared dongles micro USB port or 3.5mm audio plug, and a mobile app that allows you to control all sort of devices (TV, aircon, etc…) from your smartphone. Over three years later, more and more phones are now deprived from the audio jack, and micro USB ports have given way to USB type C ports, so that solution does not work anymore on newer phones. Some of the recent phones like Xiaomi Mi A1 integrate an IR transmitter, but for others, Zazaremote’s developer (Tiqiaa) has apparently not come up with a USB type C version, but just sells micro USB to USB type C adapters, not the most convenient. Upon further research, I eventually found a USB type C IR transmitter for smartphone sold for about $7 on FastTech. The brand name is “ROCK”, …

RedRat-X IR, Bluetooth & RF4CE Box Can Control Multiple TVs and Set-top Boxes

IR blasters can be used to control multiple IR devices through infrared, or other interfaces, for example DVR can use such device to change the channel of a set-top box just before recording.
