TTP223B Digital Touch Sensor Capacitive Touch Switch Module
This sensor based on a touch-sensing IC which is TTP223B capacitive touch switch module. It is low power consumption, its output is low at its normal stage. When anyone touches the finger on the sensor the module output goes high. It is compulsory to touch for 112 seconds otherwise it switches to the low power mode.
Its initial stage is low, high touch and if don’t touch than it goes Low. It could be installed in such as surfaces like plastic, a glass of non-metallic materials.
The interface of the Touch Sensor:
Its control interface consists of a total of three 3 pins.
- GND to ground
- VCC is the power supply
- SIG is a digital signal output pin
It has a Green LED as a power indicator
It is similar to a fingerprint icon inside the area; the Client can touch the trigger finger.
It consists of 4 M2 screws positing hole. Its diameter is 2.2mm, it’s positioning of the module can be installed easily to get the inter-module combination.
Features of TTP223B Digital Touch Sensor Capacitive Touch Switch Module:
It is low power consumption
Its power supply is between 2 to 5.5V DC.
It can replace the traditional touch of a button.
It has 4 M2 screws positioning holes for installation.
Specifications of Touch Sensor:
Its power supply voltages are 2, 3, 5.5V.
Its output high voltages are 0.8VCC.
Its output low voltages are 0.3VCC.
Its response time is 6o mili seconds.
Its output pin sink current is VCC = 3V and VOL = 0.6V : 8mA
Its output pin pull up current is VCC = 3V, and VOH = 2.4V: 4mA.
Its response time within low power mode is 220 mS.
