AM2301 Temperature/Humidity Sensor


Availability: In Stock

The AM2301 is a great weather sensor package. This uses 1 digital input to the microcontroller and provides temperature accurate to +/- 0.5°C and humidity accurate to +/- 3% relative humidity. The sensor will operate on 3 to 5VDC and its logic level output will be the same as the input voltage. It is not weather resistant so it should be sheltered from direct exposure to the elements.

The AM2301 Temperature / Humidity sensor is an integrated capacitive humidity sensing element and thermistor temperature sensor capable of delivering accuracies of +/- 0.5°C for temperature and +/- 3% for relative humidity. Compatible with both 3V and 5V systems, the AM2301 easily interfaces with a wide range of microcontrollers and IoT devices.

With attributes such as low power consumption, quick response time, and compact design, the AM2301 is optimally suited for diverse applications like weather stations, home automation systems, and agricultural monitoring. Its stability, accuracy, and cost-effectiveness make it the go-to choice for users seeking accurate environmental data on a budget.

Though not weatherproof, the sensor can be easily protected from the elements when deployed outdoors. Moreover, the AM2301’s integrated 5.1K resistor eliminates the need for an additional pull-up resistor, streamlining its implementation in a variety of projects and systems.
