CL-30 Pinout

Pinout Usage and Notes:

The CL-30 has three pins: Vcc, GND, and OUT. The Vcc pin should be connected to the power source, and GND should be connected to the system ground. The OUT pin provides the light level signal, which can be either an analog voltage or a digital signal depending on the version of the sensor. Make sure to connect the OUT pin to the appropriate input on your microcontroller or circuit. When integrating the CL-30, ensure that the power supply is stable and within the recommended voltage range to avoid damaging the sensor.

CL-30 Equivalent Models

Replacement Considerations:

When considering a replacement for the CL-30, be sure to compare the light detection range, output type, and power supply requirements. The TSL2561 provides excellent precision but has a smaller range compared to the CL-30. The APDS-9301 is a more compact alternative with lower power usage, but it also comes with a reduced light range. If you need a sensor for specific environmental light sensing, the BH1750 could be a better fit, though it offers a smaller light range. Always ensure the replacement matches your system’s voltage and sensitivity needs.

CL-30 Thermistor Circuit Analysis

The CL-30 is an NTC (Negative Temperature Coefficient) thermistor designed primarily for inrush current limiting in power supply circuits. Its resistance decreases as it heats up, allowing it to limit the initial surge of current when a device is powered on. This characteristic helps prevent damage to components and avoids tripping circuit breakers or blowing fuses.

Typical Application Circuit

In a typical application, the CL-30 is placed in series with the AC power input to the device. Upon initial power-up, the thermistor’s high resistance limits the inrush current. As current flows through it, the thermistor heats up, causing its resistance to drop, and allowing normal operating current to pass through.
