Sonoff SC is an ESP8266 and ATMega328(Arduino) based indoor WiFi environmental monitor station. It detects current temperature, humidity, light intensity, air quality (particulate), and even sound levels (noise pollution), and directly sends realtime data to iOS/Android APP EWeLink. Its power supply is micro USB 5V.
The most significant function of SC is that it supports to set all kinds of smart scene to trigger on/off other device. With the environment data, we can use smart scene to make traditional home appliances intelligent. The smart scene allows to set one or more Sonoff SC conditions (temperature, humidity, light intensity, air quality and sound levels), when the conditions meet the preset level, it can trigger to turn on or off other devices, say Sonoff.
That means we can dig more possibilities by using Sonoff SC. For example,by collecting air quality data, we can set up scene to turn on/off ventilating fan to guarantee fresh air indoor; Lighting can be automatically adjusted to the most suitable brightness according to the changing house light.
If the collected data does not exceed the update threshold, the data will be updated every two minutes. If there is a significant change, it will updated to the AWS IOT server.
The Sonoff SC is hacker-friendly, we use the ATMega328 controller with Arduino code to read the sensor data, and use the ESP8266 for wifi communication
Display realtime environment around:
Realtime temperature(0-100℃) and humidity(%) （Temperature deviation ± 2 ℃, Humidity deviation ±20％)
Light level: dusky, normal, bright
Air quality: good, moderate, unhealthy
Sound level: quiet, normal, noisy
Support smart scene to trigger ON/OFF of another smart home device
1. Download “eWeLink” app and Install the APP.
Search “eWeLink” in APP Store for iOS version or Google play for Android version.
Sonoff SC supports 5V usb power input. Simply plug the micro usb inside the usb port.
1.Enter WiFi pairing state: Press the black button for 7 seconds until the LED blinks blinks 3 times and on repeatedly.
2.For Android, please directly click the “Add” icon on EweLink to search device, click next.
For iOS, please go to phone Setting>WiFi>connect the WiFi begins with ITEAD-******, enter default password 12345678. Go back to eWeLink, select the pairing method, click next.
The App will auto-search the device.
3.Input your home SSID & password:
3.1 Your SSID must be letters and or numbers.
3.2 If no password, keep it blank.
3.3 Now eWeLink only supports 2.4G wifi communication protocol, 5G-WiFi-router is not supported
4. Next, the device will be registered by eWelink and add it to your account，it takes 1-3 minutes. Once it is being added, the light will keep on.
5. Name the device to complete.
6.Maybe the device is “Offline” on eWeLink, for the device needs 1 minute to connect with your router and server. When the green LED on, the device is “Online”, if eWeLink shows still “Offline”, please close eWeLink and re-open.
4.1.Display the realtime temperature, humidity, light intensity, air quality (particulate) and sound levels.
- Realtime temperature(0-100℃) and humidity(%)
- Light level: dusky, normal, bright
- Air quality: bad, moderate, unhealthy
- Sound level: quiet, normal, noisy
Sonoff SC supports to set up all kinds of smart scenes to trigger on/off other device. You can set one or more conditions, when temperature, humidity, light, noise, air quality lower or larger than the preset level, it will trigger to turn on/off the triggered device(such as Sonoff)
Got to the device list, tap on the up upper right corner, then tap on “Scene” . Click “+” to add scene. Input a name for the new scene, and add trigger condition. Select the Sonoff SC and save. Next, enter the triggered device’s action: ON or OFF, save it. Last, save your scene.
Owner can share the devices to other accounts, but both of them must stay online at the same time.
One device one owner. Other people can not add the devices that have already been added.
