Sensor Module

About sensor…

Specifications

  • Two 3,5mm jacket inputs
  • 5 front pins

Current

Current transformers (CTs) are sensors that are used for measuring alternating current. They are particularly useful for measuring whole building electricity consumption (or generation for that matter). The split core type such as the CT in the picture above, is particularly suitable for DIY use it can be clipped straight on to either the live or neutral wire coming into the building without having to do any high voltage electrical work.

Specifications

  • Input Current: 0~30A AC
  • Output Mode: DC 0~1V
  • Non-linearity:2-3%
  • Build-in sampling resistance(RL): 62Ω
  • Turn Ratio: 1800:1
  • Resistance Grade: Grade B
  • Work Temperature: -25°C ~ ﹢70°C
  • Dielectric Strength(between shell and output): 1000V AC/1min 5mA
  • Leading Wire in Length: 1m
  • Open Size: 13mm x 13mm

Encoder

A rotary encoder is a type of position sensor which is used for determining the angular position of a rotating shaft. It generates an electrical signal, either analog or digital, according to the rotational movement.

By rotating the rotary encoder can be counted in the positive direction and the reverse direction during rotation of the output pulse frequency, unlike potentiometer count, this rotation counts are not limited. With the buttons on the rotary encoder can be reset to its initial state, that starts counting from 0.

Specifications

  • Size: 31 x 19 x 29mm
  • Pulse circle: 20

Electrical connection

Both Encoder and Current connection is connected to ports: GPIO4, GPIO5, GPIO6, GPIO7, A0
