CT1270 AC/DC Current Sensor
- Supply voltage: 5v DC
- Output: Analog Dc Voltage
- Small size
- Pass Wire Through Hole
- Get DC analogue Voltage Vcc and GND
- Compatible with Arduino, Raspberry Pi, AVR, ARM,8051, PIC
A current sensor is designed to detect electric current AC/DC in a wire and thus generates a signal proportional to it. This generated signal could be analogue voltage or current or even digital output. Current Sensor basically used to measure and calculate the amount of current applied to the conductor without affecting the performance of the system. This current sensor operates at a supply voltage of 5V in which output is proportional to AC or DC current. CT1270 is used in a wide range of applications where sensing and controlling current flow is fundamental such as displaying the measured current in an ammeter. And also stored for further analysis in a data acquisition system or can be utilized for control purposes.
The present output current signal is read via the analogue I / O port of a microcontroller or an Arduino. Moreover, this current sensor module works perfectly with Arduino, Raspberry pi, AVR, ARM,8051, PIC and can be interfaced easily.
