WiFi Temperature Sensor featuring 4Duino-24

By | 14th October, 2016|Categories: Medium|4 Comments

In this project we will quickly create a ‘temperature monitor’ that measures the ambient temperature of a room or an outdoor space. The temperature is measured by TMP35 temperature sensor and is displayed on the 4Duino screen. The data is also sent to Thingspeak IoT platform which enables data logging over a period of time. [...]

4Duino Ultrasonic Sensor

By | 12th August, 2016|Categories: Medium|Tags: , , , , , |1 Comment

In this project we will measure the distance of the nearby object using TS601-01 Ultrasonic sensor and 4Duino. An ultrasonic sensor has a transmitter (sends ultrasonic signals) and a receiver (receives the ultrasonic signal after it bounced off nearby object). The sensor estimates the distance of the object by transmitting a signal and determining how [...]
