# NodeMCU_PIS ## Description This project combines one soil sensor (resistive or capacetive), one 5V pump in a water tank and a floating switch to detect the water level. Depending on the soil measurment and the configured nominal value the pump can be controlled while the floating switch prevents the pump from running dry. All configurations can be controlled via MQTT. ## Project Details - **Owner:** jecstronic - **Created:** 9/20/2021 - **Last Updated:** 1/19/2022 - **Visibility:** Public ## Key Components ### ? — Label **Pins:** - P1 - P2 ### ? — [Nodemcu-12E ESP8266](https://www.flux.ai/jharwinbarrozo/nodemcu-12e-esp8266~5t.md) - Datasheet URL: https://components101.com/development-boards/nodemcu-esp8266-pinout-features-and-datasheet - Manufacturer Part Number: Nodemcu-12E ESP8266 **Pins:** - 3V3 - 3V3 - 3V3 - A0 - CLK - CMD - D0 - D1 - D2 - D3 - D4 - D5 - D6 - D7 - D8 - EN - GND - GND - GND - GND - RST - RSV - RSV - RX - SD0 - SD1 - SD2 - SD3 - TX - Vin ### ? — Label **Pins:** - P1 - P2 ### ? — Label **Pins:** - P1 - P2 ### ? — Label **Pins:** - P1 - P2 ### +5v — [+5V Power/Voltage](https://www.flux.ai/adrian95/plus5v-powervoltage~raj.md) **Pins:** - +5V ### +5V — [+5V Power/Voltage](https://www.flux.ai/adrian95/plus5v-powervoltage~raj.md) **Pins:** - +5V ### A0 — Label **Pins:** - P1 - P2 ### CLK — Label **Pins:** - P1 - P2 ### CONTACT — Label **Pins:** - P1 - P2 ### CS — Label **Pins:** - P1 - P2 ### DHT — Label **Pins:** - P1 - P2 ### DIG — Label **Pins:** - P1 - P2 ### GND — Label **Pins:** - P1 - P2 ### J1 — [Connector-02x02-Counter-Clockwise](https://www.flux.ai/adrian95/97f3d650-165e-4674-0e89-02bf56318ff2~qxu.md) - Part Type: Connector **Pins:** - Pin_1 - Pin_2 - Pin_3 - Pin_4 ### J2 — [532530370](https://www.flux.ai/jecstronic/532530370~bsw.md) - Datasheet URL: https://www.molex.com/molex/products/part-detail/pcb_headers/0532530370 - Part Type: 532530370 - Part Type: HEADERS - Manufacturer Part Number: 532530370 - Package or Case Code: SPK-53253 **Pins:** - 1 - 2 - 3 ### LED — Label **Pins:** - P1 - P2 ### MISO — Label **Pins:** - P1 - P2 ### MOSI — Label **Pins:** - P1 - P2 ### RELAY — Label **Pins:** - P1 - P2 ### RxD — Label **Pins:** - P1 - P2 ### TxD — Label **Pins:** - P1 - P2 *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/jecstronic/nodemcupis~4o7](https://www.flux.ai/jecstronic/nodemcupis~4o7).* --- *Generated from [https://www.flux.ai/jecstronic/nodemcupis~4o7](https://www.flux.ai/jecstronic/nodemcupis~4o7)*
