The CJMCU-811 is an ultra-low-power digital gas sensor that integrates a sensor and a CCS801-bit MCU with an analog-digital converter (ADC) for detecting indoor air quality, including carbon monoxide (CO) and a wide range of Volatile Organic compounds (VOCs).
Feature:
Ultra-low power consumption can be used in battery powered equipment
Despite showing available on the website and accepting my order, they called to tell me that the order was not available.
I had to then concede with another lower rated battery.
The issue doesn't end here.
I was supposed to get a refund for the difference in pricing, but despite reminders and calls (which were not answered), I didn't get any refund until I almost filed a police complaint against them.
Case is nice and sturdy all ports are perfectly aligned it has enough room for hat , especially if you want use Geekworm X1002 PCIe to M.2 2280 hat for nvme.
The only thing is missing is heat dissipation cut outs on the top of the case , If it has heat dissipation holes on the top it will be much better however case is having many cutout on the front bottom and right side but , for active cooler to release instant heat top side cutout will be much better .
Next thing it will be better If it comes with rubber feet so that in case we don't want to mount on wall we can place on table little bit risen up from the surface.
It comes with rail mount and wall mount which is very good.
with offical RPI5 active cooler and if cooler is not running (only passive heat release)the ideal temp of pi 5 stays around 53 degree Celsius when room's ambient temperature is around 18 degrees , and its running on raspberry pi os .
what will be the temp. on summers that i yet to experience.
