The switch is attached to a Wemos D1 mini through a pull-up resistor. The switch is pressed all the time till the filament is broken and then the switch connects pin D1 of the Wemos D1 to GND. When this happens the Wemos D1 sends a signal to IFTTT and IFTTT sends an alert to my phone. Filament sensor.
After Two weeks i got my package and started hacking into the connections and building a replacement for the included Controller. I Replaced it with a Wemos D1 Mini and a a DHT22 Temperature Sensor (had a DHT22 laying around, works okay so far, maybe repalced by a better one in the future).You need two wemos d1 mini boards, one acting as the 'sensor', the other one as the 'lamp'. The wemos d1 mini acting as 'lamp' should be fitted with an RGB shield. 6.2.
We also added a reed switch to the door so that you know it is closed. Hardware. For the reed switch we used this alarm type switch that mounts to the ground with a magnet mounted on the bottom of the rolladoor. For the electronics we used a Wemos D1 Mini and a matching Relay Shield. The WeMos D1 Mini DHT-11 Temperature/Humidity Sensor Shield includes the popular sensor for measuring temperature and relative humidity locally. The WeMos D1 Mini DHT-11 Temperature/Humidity Sensor Shield is designed so that pin D4 on the WeMos D1 Mini v2 board is connected to the data pin of the sensor.Sep 29, 2017 · WeMos D1 mini and WeMos D1 mini PRO are two small boards that use the low-cost Wi-Fi enabled ESP8266 chip. The two boards, along with a variety of shields (such as a button shield, relay shield, or battery shield) are produced by WEMOS, a Chinese IoT products manufacturing company. The WeMos D1 mini is priced at $3.50, and the PRO at $5 (the ...
Jul 23, 2020 · The values from sensors are displayed on the mobile phone, using Blynk IoT framework. Ingredients: ESP8266 WeMos D1 mini board. RHT03 temperature and humidity sensor. Sensor specifications: 3.3-6V Input; Humidity from 0-100% RH, ±2% RH accuracy-40 – 80 degrees C temperature range,±0.5 degrees C The door sensor is a separate Arduino that talks to the Wemos D1 mini via NRF24L01. I found that shorting the two connections on the garage door opener toggles the door. A simple relay (Normally Open, Active LOW) is used to achieve the same from Arduino. Wemos D1 Mini compatible Battery Shield V1.1.0, for a single rechargeable Lithium cell 3.7V. Charging current adjustable 0.5A or 1.0A. The on board step-up DC-DC boost converter generates the output voltage of 5V for the Wemos D1 Mini environment.
