This Gravity Universal Terminal Sensor Adapter V2.0 is a great solution for easy connection. It can be accessed by both digital input modules and analog input modules. When combined with an Arduino sensor expansion board, it works like a charm. Compared to the old version, we've made a smart improvement. We've added a 10K resistor between A & B, and A & C respectively. This means you don't need to connect an additional resistor when your sensor requires a pull - up or pull - down resistor. For more on why a pull - up or pull - down resistor is needed, refer to 'Understanding pull - up and pull - down resistors'. Generally, this terminal offers a super easy way to connect a switch or any modules that need a pull - up/down resistor to a microcontroller. Specifications: Voltage is +5 V, current is less than 1000mA, and it has a size of 22x34mm (0.87x1.3 in). Documents include a Wiki Doc and a Schematic. The shipping list contains one Terminal Sensor Adapter V2.0.
Using the Gravity Universal Terminal Sensor Adapter V2.0 is a breeze. First, connect it to your digital or analog input modules. If you're using it with an Arduino sensor expansion board, just combine them together. You don't have to worry about adding extra resistors because we've already taken care of that for you. When connecting a switch or other modules that need a pull - up or pull - down resistor, simply use this adapter to connect them to your microcontroller. As for precautions, make sure the voltage you apply is +5 V and the current is less than 1000mA to avoid any damage. For maintenance, keep it in a dry and clean place. If there's dust on it, you can use a soft cloth to gently wipe it. And always refer to the Wiki Doc and Schematic if you have any questions during use.
