4 Channel ESP8266 Mains Current Sensor – Wemos – Current – SCT013 – 100A/50mA
Mottramlabs.com Keeping it simple since 2018 Description: A 4-Channel mains power sensor using a current transformer and either a Wemos D1 mini or ESP-12 module (not included). The transformer used is a "Current Transformer AC current sensor 100A SCT-013-000" available on eBay. This is a 4-channel version of our popular Wemos power sensor. The board uses the ESP8266 onboard A/D and uses a CD4052 multiplexer to select the channel to be measured. An onboard 3.3V regulator provides power for the ESP8266, input votage 12V DC. Version 3 boards have the addition of cut links that remove the 22R burden resistor from the circuit, this option makes using 1V type CT clamps very easy Warning: No direct connection should be made to any high voltage, use the Current Transformer as the manufacture recommends Specification: ● PCB Size: 94mm x 41mm ● CT Inputs: 4off 3.5mm Stereo Jacks (CT Inputs) ● DC Input: 2.1mm Jack (12V DC) Included: ⬦ PCB Assembled and Tested (Wemos not included) Don't forget to look at My Other Boards Also Available: A simple 3D printable case design is available on thingiverse.com, search for Dimwit-Dave. Also the schematic is available. --> Terms and Conditions ● The customer is responsible for all customs duties and import taxes ● Payment must be received within 4 working days of purchase, however if this is not possible, please let us know to discuss solutions. ● You will be notified on the day that your goods have been despatched via e-mail. ● Once you receive your goods, please inspect them for any damage during transit, and report the said damage within 24hrs via e-mail. ● If all is well please leave feedback, so we are aware that you have received your goods. ● It is the customers responsibility to ensure that payment is received in the due time as listed above. ● All goods are sent via Royal Mail second class post. ● Goods will be despatched within 24 hrs of cleared funds, subject to the conditions listed in the payment section above. ● We accept no responsibility for goods delayed due to the services of the Royal Mail.
