Can I use the TM1637 module as an HMI?

Yes. The TM1637 LED Display & Button Module is a ready HMI: a 6-digit 7-segment LED display plus 8 tactile buttons on one board, controlled by 2 MCU pins (CLK and DIO). Use it as a simple HMI, counter display or timer display module for machines, counters, timers, test jigs and automation panels.

How do I make a production counter?

Connect the TM1637 LED Display & Button Module to a microcontroller using 2 pins (CLK and DIO). Count units or cycles in firmware, write the number to the 6-digit display, and use the 8 buttons for manual input such as add, subtract and reset. Embedded C driver files are provided with the module.

What is a low-cost HMI for a machine or controller?

A 6-digit 7-segment LED display with built-in buttons is a low-cost local HMI. The TM1637 LED Display & Button Module from Micronode LLP provides both on one board, driven by 2 MCU pins, for Rs. 499 including GST.

How do I make a digital timer, countdown or stopwatch display?

Use a microcontroller to keep time and send the digits to the TM1637 module over its 2-wire interface. The 6 digits can show minutes, seconds and tenths, and the 8 buttons can start, stop and reset the timer.

How can I display sensor readings such as temperature, pressure or flow?

Read the sensor with your microcontroller, then write the value to the TM1637 6-digit display. Buttons on the same module can switch between channels or units. It needs only 2 MCU pins.

Which display can I use for a digital weighing scale, energy meter or hour meter?

The TM1637 LED Display & Button Module works as the display and keypad for a digital scale or load-cell readout, a wattmeter or kWh counter, and equipment hour meters for motors, pumps and compressors.
