BAR-GRAPH-VOLT-METER-RANGE-0-5V-DC-001

Tiny Bar-Graph displays provide a Red color bright, easy to read display of Voltage range of 0 to 5V.  This Bar-Graph has 20 segments in single color and display 0 to 5V DC. The Barograph Voltage monitor is based on PIC microcontroller with 10 Bit resolution ADC.  This high performance measurement provides unique capabilities and can be used in various applications. The Bar can display 0 to 5V with 20 LED with 0.25V (Approx.)   resolutions.  Each LED output provided with Solder- jumper for output set point can be configured for control, alarm, Relay.

Features

  • Supply 7.5 V to 18V DC (Direct 5V Input Possible)
  • Test Voltage Input 0 to 5V
  • Output Display 20 Color RED SMD LEDs
  • Compact Board with SMD Components
  • Supply input Header Connecter
  • On Board 5V Regulator
  • Resolution 0.25V Approx.
  • Onboard Trimport to Calibrate The Display Range.
  • Solder Jumper on each LED for Output Control, Alarm, and Relay
  • PCB Dimensions 75.88 X 26.69 MM

Calibration: Apply 7V to 18V DC supply, Apply accurate 5V at Input pin, Turn PR1 Trimport CCW/CW so all LED glow.

I’m looking for something similar to measure 0-12vdc. The form factor must be approximately 2.5x1cm

kamran

I’m looking for something similar to measure 4-20 mA and 0-20mA

Thank you

Ken

Can I purchase this? Assembled yeast to implement?

Kliment Stefanov

I’d like to have four of those please. Any cost estimate?

Michael

I prefer something like this but for the voltage curve input to follow and only light up the LEDS are in that curve.

Michael

i’m a private project builder, i’m looking to buy either 1 or about 10
