CT sensors are sensors for measuring alternating current, useful for determining total building electricity consumption (or generation). The picture above showcases the split core type of CT, ideal for DIY since it can be attached directly to the live or neutral wire without carrying out any complex electrical work. Features: Applications Suitable for the current measuring Monitoring and protection of AC motor Lighting equipment Air compressor Specification: Input Current: 0~60A AC Output Mode: 0~1V Non-linearity: ±3% Build-in sampling resistance(RL): 31Ω Resistance Grade: Grade B Work Temperature: -25°C ~ ﹢70°C Dielectric Strength(between shell and output): 1000V AC/1min 5mA Leading Wire in Length: 1m Open Size: 13mm x 13mm Fire resistance property: in accordance with UL94-VO SCT-013 Series CT Senors - Introduction CT Sensors - Interfacing with an Arduino CT Sensors - How to build an arduino energy monitor
