The Broadlink A1 is a detector which can monitor the situation including VOC, voice, light, humidity, temperature, and so on. Users can check the indoor situation through their smartphone anywhere at anytime. Moreover, in conjunction with the e-Air smart detector, users can preset the actions to take under the situation in the apps “e-Control”. For example, the dehumidifier will turn on automatically when the humidity is over 80%. Furthermore, you can preset the time that actions will be automatically taken.
