MicroCrystal RV-8803 – A Really Accurate RTC June 17, 2019- RTC chips traditionally were the domain of Maxim and NXP. Switzerland-based MicroCrystal recently made quite a buzz with its RV-8803, which offers simple integration, an I2C interface and extreme accuracy. Let us start out by looking at a system overview. Figure one shows how this I2C RTC is made up internally – interested observers note […] Analog Devices’ LTM2887 – If a Digital Bus Needs Galvanic Isolation June 15, 2019- In theory, digital buses are intended to connect things to one another. Sadly, one sometimes wants but a logical connection – in many cases, galvanic isolation helps out. Should you ever feel like isolating very fast buses, definitely give the LTM2887 a chance. From a technical point of view, Linear Technologies attempt at entering the […] AVAGO APDS-9008 or APDS-9005-020 – Keeping an Eye on Ambient Light June 14, 2019- Recent times saw quite a bit of interest for part numbers such as the APDS-9008 or APDS-9005-020 – they are a very interesting type of ambient light sensor. One of the oldest questions in regards to light sensors involves their spectral sensitivity. If a part is to output but one voltage level, the conversion between […] STMicroelectronics’ LIS2DH12 – Low Power Motion Sensing June 12, 2019- Apple’s iPhone introduced gyroscopic sensors to a wider range – before that, accelerometers were not commonly found in consumer hardware. STM sells excellent parts which, however, get little media attention – time to take a look at the LIS2DH12. Integrating the part into your circuit as an MPU6500 alternative or MPU9500 alternative is not difficult. […] Panasonic AMG8833 – FLIR for cheap June 7, 2019- FLIR made infrared thermal sensors cool – sadly, their parts are all but cheap (and suffer from export control problems). Panasonic’s Grid-EYE family is a low-resolution alternative which comes at significantly lower cost. From a technical point of view, Panasonic’s image sensor could not be simpler. We are looking at an 8×8 sensor with an […] DipTronics DTS-62R-V – Small Switch, Very Big (and Very Cheap) June 5, 2019- When yours truly was but a lowly cadet, various US manufacturers produced (pricey but quite reliable) switches. Chinese vendors recently started to catch up – seeing the DTS-62R-V top our customer interest list shows that the run stage of the crawl-walk-run cycle is reached. DipTronics has been around the Asian switch market for ages, exhibiting […]
FLIR made infrared thermal sensors cool – sadly, their parts are all but cheap (and suffer from export control problems). Panasonic’s Grid-EYE family is a low-resolution alternative which comes at significantly lower cost.
From a technical point of view, Panasonic’s image sensor could not be simpler. We are looking at an 8×8 sensor with an individual resolution of eight bits – it can provide either one or ten frames per second via an attached I2C bus.
Objects can have temperatures of 0 to 80 degrees centigrade for the high gain model, while the low gain version of the sensor allows for an extended temperature range of -20 to 100 degrees. Interestingly, the operating temperature of both sensors is maxed out at 80 degrees, which adds the requirement of at least some kind of thermal insulation.
If you ever felt like an I2C thermal sensor…
The relatively small housing size makes AMG8833 hand soldering difficult. Panasonic addresses this problem via the Grid-EYE Infrared (IR) Array sensor Evaluation Kit – it combines the sensor with a Bluetooth module, both of which can then be deployed comfortably. The evaluation kit, furthermore, comes with a wide array of software libraries found at by Clicking Here
Panasonic provides a wide variety of tutorial information on handling the device. Most of it can be accessed via the DigiKey portal found at https://www.digikey.com/catalog/en/partgroup/amg88-series/58939 – visit it to feast your eyes on datasheets, videos and more.
Finally, keep in mind that the 3V3 AMG8833 does not stand alone. The Panasonic AMG8834 is a low-gain version of the part, while the AMG8853 and AMG8854 are 5V infrared thermal sensors.
