The TTP223 Capacitive Touch Sensor Module is a compact, digital touch switch that replaces mechanical buttons. It detects finger touch through capacitive sensing and outputs a stable HIGH/LOW signal, suitable for Arduino, Raspberry Pi, NodeMCU, and DIY electronics projects.
The Voltage Sensor Module 0–25V is a precision voltage detection module designed for microcontrollers like Arduino, Raspberry Pi, ESP8266, and NodeMCU. It uses a voltage divider circuit to safely measure DC inputs up to 25V and convert them into a readable 0–5V output for ADC pins.
The W1209 Temperature Controller is a compact and intelligent digital thermostat capable of controlling temperatures from –50°C to 110°C. Featuring an onboard NTC 10K sensor, relay output, digital 3-button interface, and LED display, it is ideal for DIY incubators, aquarium heaters, temperature-controlled fans, and automation projects.
The Weighing Scale Fully Assembled Kit includes a pre-calibrated 5kg load cell, premium weighing platform, and HX711 high-precision 24-bit ADC module. Ideal for digital weighing scales, Arduino projects, IoT systems, lab experiments, and automation applications.
