ESP8285 Infrared Board

Leave a comment

I've once again found a small board with an ESP on the fast Ali. This time, however, it's an ESP8285, which apparently only differs from the ESP8266 in its internal 1MB flash memory. This board costs just under 4 Euros, has no USB port, and must be programmed with applications using a programmer. On the other hand, it has an IR receiver and an IR transmitter and is quite small. The ports are not brought out via pins, but it seems quite possible to solder cables to the ESP board. You'll find the data as always in the following chapters.

HC-SR501 PIR motion sensor

2 Comments

The HC SR501 is a 360° infrared motion sensor. It has a detection radius of 120°. When movement is detected within the measuring range, it switches a pin to 3.3V and holds it for a set hold time (on-time). Sensitivity and hold time can be adjusted using the respective rotary knobs. Facts Technical Data Description Value Operating voltage 5-20V Current < 60µA Output voltage (on/off) 3.3V/...

And another Arduino shield with something on it. This could be particularly interesting for beginners. A four-digit 7-segment display, 4 LEDs, a buzzer, a potentiometer, a few buttons – what more do you need? If you have too much money, you can also populate the APC220 port and flash via remote USB. How nice it is to have a new...
