ZMPT101B is a voltage sensor module designed to measure AC single-phase voltage. It's widely used in projects that need to monitor or control AC voltage levels, such as in energy meters, power systems, or home automation.
Specifications:
- Type: AC Voltage Sensor
- Voltage Range: 0V to 250V AC (single-phase)
- Operating Voltage: 5V DC (for the module)
- Output: Analog signal (corresponding to the AC voltage level)
- Accuracy: ±1-2% (depends on calibration)
- Frequency Range: 50Hz to 60Hz
- Load Current: Max 10mA (sensor output current)
- Operating Temperature: -40°C to +85°C
- Size: Small and compact (about 3cm x 2cm)
- Isolation: Optocoupler-based isolation for safety and accurate readings
Uses:
- Energy Meters: Used in smart meters for measuring AC voltage in household or industrial applications.
- Power Systems: Monitor voltage levels in power distribution systems.
- Home Automation: Control and monitor home appliances based on AC voltage.
- Voltage Sensing: Can be used to detect voltage fluctuations or under-voltage conditions in electrical systems.
