Wireless Temperature Sensor with Digital Display

Product Code: PS-4201


Our modern thermometer just keeps getting better. We’ve added a bright organic light-emitting diode (OLED) display on the sensor for users who want the ability to see instant data readings without the need for additional software, even in bright outdoor explorations. This sensor still provides the option for quality wireless temperature data transmitted live for continuously monitoring, logging, and plotting temperature measurements on nearly any device. When lab-time ends but the experiment continues, students can set the sensor to log data autonomously for days, weeks, or months, then download that data for analysis later. This durable, wireless sensor features a stainless steel probe for the most demanding of applications, and it contains a rechargeable battery via a standard USB C cable. It can be used in a wide array of experiments and activities because it measures small but significant temperature changes produced by chemical reactions, convection currents, and even skin temperatures.


  • Simply charge, pair and go, no cables or adapters to manage
  • Variable sampling rate for capturing small, fast changes or experiments that run for hours, days, or weeks
  • Bluetooth® connectivity and long-lasting rechargeable battery
  • Logs temperature data directly onto the sensor for long-term experiments
  • Dust, dirt, sand and water resistant

What’s Included

  • 1x Li ion 300 mAh rechargeable battery
