- Temperature Sensor: LM35 sensor
Connections
Connecting the LM35 sensor to the Bolt
Step 1: Hold the sensor in a manner such that you can read LM35 written on it.
Step 2: In this position, identify the pins of the sensor as VCC, Output and Gnd from your left to right.
In the above image, VCC is connected to the red wire, Output is connected to the orange wire and Gnd is connected to the brown wire.Step 3: Using male to female wire connect the 3 pins of the LM35 to the Bolt Wifi Module as follows:
