Information

KY-040 Rotary Encoder
The current posion of the rotary switch is given out coded on
the output.
① - [CLK]
② - [DT]
③ - Buon
④ - +V
KY-050 Ultrasonic-Distancesensor
If a signal (falling peak) is given to the trigger-input, a distance
measurement is executed and given out as a PWM-TTL signal to the
echo-output.
Measureable distance: 2cm—300cm Measurement-resoluon: 3mm
① - GND
② - Echo
③ - Trigger
④ - +V
KY-051 Voltage Translator / Level Shier
This level-shier transfers digital signals from a voltage into another.
4 channels are available which can be used.
PIN-assignment is printed to the
module-board
KY-052 Pressuresensor / Temperaturesensor [BMP280]
This pressure sensor measures the air pressure at the sensor output
(small hole on the silver sensor housing) and outputs the result coded
on the I2C bus.
A soware is necessary to use this sensor
① - SD0
② - CSB
③ - [SDA]
④ - [SDL]
⑤ - VCC GND
KY-053 Analog Digital Converter
With appropriate commands to the I2C-Bus, up to 4 analog inputs can
be measured to an accuracy of up to 16 Bit. The result is given out
coded to the I2C-Bus.
