3V-5.5V HC-SR04P Ultrasonic Ranging Module (sensor ultrasonic 3V)
Perfect for use with your 3.3V system like NodeMCU, Wemos, Raspberry pi and micro:bit
AC 220V 1 Channel Optocoupler voltage detection sensor (AC detection 1 sensor)
This module can be used to detect if your 220V AC connection is on. A small microcontroller like Raspberry Pi Pico or Arduino can be used for instance to monitor and report loadshedding or tripped circuit breakers.
USB-C PD/QCIAFC Fast charge decoy trigger PD3.0 (PD/QCIAFC Decoy Trigger)
The Decoy Trigger handles the complex "handshake" conversation between a power source and a device. By mimicking the signals of a high-end smartphone, it tells the charger to switch from the standard 5V up to 9V, 12V, 15V, or 20V.
Kitronik 'Mini' Prong Soil Moisture Sensor for BBC micro:bit (KT moisture prong mbit)
The Mini Prong soil moisture sensor for BBC microbit is a sensor board that can be connected to a BBC micro:bit with crocodile clips to monitor the moisture present in the soil.
