attic_fan_control

Uses: attic_fan_remote_sensor : ESP01 Master & esp01 remote, DS18B20, ESPNOW, 2n2222-SSR-25 DA: Control "relay" SSR-25 DA to turn on/off a box fan that covers an attic access in the ceiling. Using two DS18B20 temp sensors, one in the Attic and one in the hallway AND a third remote esp01 managing a DS18B20 the Attic esp01's C++ will determine whether to turn on / off the solid state module for the fan.

attic_fan_remote_sensor

Battery powered ESP01 espnow: BME280 readings and MCU vcc. 18ua deep sleep & 212ms 66ma transmit. See Attic Fan Controller Project

esp32_cabinet_environment

esp8266_cabinet_environment

Same as ESP32_Cabinet_environment - modified for ESP01

esp8266_home_airpressure_equalizer

ESP8266 DOITAM, BMP28, BME280, DS18B20, Servo, 128x32 OLED, 2x water flow meters using : interrupt driven tick counter. Monitor and display inside, outside air pressure & temperature, cold water & hot water usage, hot water tank temp and send (broadcast), using espnow to remote esp01 for OLED display. Also host web pages for display of status and a settings page and in case of WiFi connectivity problems, host a WiFi setup page. The ESP manages a servo and PWM computer cooling fan used to open/close 4" modified dryer backflow damper in order to equalize air pressure in the furnace/hot water tank room in my home. Hopefully reducing cold air drafts in the winter.

esp8266_linked_scales_wb

HX711, 3x esp01, 3 generic 700lb bath scales. DNS, Soft AP, WebSock, espnow. Convert bath scales to use HX711 & esp01 to host web page with simultaneous reading from up to 4 scales. updated values sent using WebSock & inter esp01 communication using espnow.

esp8266_temphumidity_controller

esp8266, four relays, 2 DHT11: Individually Turn on/off four relays to control two heat pads and a humidifier based on reading from two DHT11 sensors. Web Page shows values updated using WebSock and a settings web page for user provided threshold values.
