When choosing a remote temperature monitoring system, it’s important to look past the hype and find the best possible solution for your application. I hope this post will help do just that.
Wi-Fi: A wireless protocol for sending large amounts of data as far and quickly as possible, often compromising battery life and module size. Ideas about these technologies started around 1985 but didn’t become commercially used until more than 10 years later, in 1999.
Bluetooth: A wireless protocol for sending large amounts of data over short distances, while maintaining low power and a small module size. Originally conceived in 1994 to replace RS-232 cables, which were eventually replaced by the USB cables.
ZigBee: A wireless protocol for sending small amounts of data over long distances, while using low power and a small module size.. Conceived sometime in 1998, the need arose because bluetooth and wifi were unsuitable for many applications.
IMPORTANT QUESTIONS TO CONSIDER WHEN SELECTING A SYSTEM:
- How many sensors do you need?
- What is your price range?
- Who will be responsible for the setup?
- Who will be using the system?
- Is power available or will the sensors need to be battery operated?
- Does the system need to be mobile?
- Will the monitoring be continuous or periodic? (will the sensor be used once a day or continuously)
WiFi sensors are best if you are monitoring few pieces of equipment and someone technical is available for the installation.
Bluetooth sensors work best for mobile applications (monitoring a sample in the trunk or back of a truck) for a short duration.
Zigbee sensors work best when you need to monitor many pieces of equipment in real-time 24/7 (refrigeration/HVAC equipment)
This is why we’ve chosen Zigbee for our FreshSense System
