ESP8266 with voltage regulator and dc18B20 temp sensor

Etapa 1: Recolección y Almacenamiento de Energía Entrada: tus cactus en serie (ej. 15 cactus × 0.5 V = 7.5 V). Componente clave: Supercapacitor o batería recargable de baja capacidad (Li-ion o LiFePO4, 3.7V-7.4V). Diodo Schottky entre los cactus y el capacitor para evitar descarga inversa. 🛠 Ejemplo de componentes: Supercapacitor de 5–10 F, 5.5 V o batería de 3.7 V (tipo 18650). Diodo Schottky 1N5819. Módulo cargador TP4056 (si usas batería). Etapa 2: Aumento de Voltaje (Boost Converter) Conversión de 3.7 V / 7.5 V DC a 110 V AC. Necesitas: Boost Converter (DC-DC Step-up) de hasta 300 V DC. Inversor DC-AC (pequeño, tipo mini inverter para LEDs) que convierta ese voltaje a 110 V AC. NOTA: Algunos focos LED pueden funcionar con 110 V DC directamente, si quieres evitar el inversor. Etapa 3: Detección de Noche Sensor LDR (resistor dependiente de luz) conectado a un comparador (ej. LM393) o a un microcontrolador (como un ATtiny o ESP8266 si quieres funciones extra). Al bajar la luz solar: El comparador activa un MOSFET o un relé que conecta la energía almacenada al foco.

NodeMCU V3 ESP8266 ESP-12E is WiFi development board that helps you to prototype your IoT product with few Lua script lines, or through Arduino IDE. The board is based on ESP8266 ESP-12E variant, unlike other ESP-12E, you won’t need to buy a separate breakout board, usb to serial adapter, or even solder it to a PCB to get started, you will only need a usb cable (Micro USB).
