An AC Dimmer is used to control the AC cycle. Normally, a dimmer is used to turning the power ON/OFF for lamps or heating elements, it can also be used in fans, pumps, air cleaners, etc. Makerfabs Lora AC Dimmer chopper circuit is based on Triac BT139, and zero-cross checking circuit, it detects the zero-cross points and then the Triac controlled to chop the AC. Besides, to avoid the problem of AC can not be totally shunted off with Triac, a relay is implemented to make the AC totally On/Off. On-board AC/DC module implemented, so no external power supply needed, suitable for field applications.

This Industry-grade soil remote monitor intends for these applications of agriculture, it is mainly composed of 2 parts: 1. Remote monitor station with RS485: developed by Makerfabs, it converts the RS485 signal, which is usually used in agricultural field applications, to wireless connections WIFI (if there is) or Lora, or Bluetooth. 2. Industrial-grade Soil Sensor: unlike some other maker-level soil sensors that only output analog voltage that reflects the soil status/changes but not the absolute value, this sensor measures the soil parameters such Temperature/Moisture/PH/Nitrogen/ Phosphorus/Potassium.., with calculated true output, so users can get to know the real soil parameters.
