Nobody knows for sure but it seems likely that the Rio Olympics pool maintenance team ran out of chemicals to control the pH of the water which resulted in an algal bloom turning the pool green. To prevent the same happening in the water polo pool, the maintenance team have dosed high levels of chlorine into the pool, which is now causing issues for the water polo teams.
The incident would have been prevented with the use of an online controller such as Pi’s AquaSense swimming pool controller. Plus if the chemicals had ran out, such a system would have gone into alarm and enabled the maintenance team to prevent this from happening.
Pi’s AquaSense measures pool pH and chlorine levels and controls these with chemical dosing. The AquaSense can also be accessed remotely over the internet, enabling data, alarms and setup information to be sent directly to your computer via a 2G/3G modem or via a TCP/IP Local Area Network (LAN). Maybe the Rio Olympics pool maintenance team should have purchased a Pi analyser?

A multi-variable transmitter from American Sensor Technologies provides both pressure and temperature outputs from a single process point. In addition to simplifying control systems, the Model AST46PT explosion proof pressure/temperature transmitter offers a superior pressure reading along with a temperature sensor output for less than the cost of a stand-alone temperature sensor. Ideal for low-power systems…

The Allpronix AL40/100 Laser Level Transmitter goes global this year!
The two Laser level/distance transmitter models (the AL40 and the AL100) has been developed in South Africa and will be manufactured locally and exported by Allpronix. As the model names indicate, the AL40 has a maximum range of 40 meters while the AL100 has a maximum range of 100 meters.
The AL40/100 is a non-contact level and distance measuring instrument designed for granular materials an opaque liquids. The narrow beam of a laser allow direct aiming at the target material without interference from structures or falling material.
This instrument is the first of its kind to have an on-board LCD screen and a programming keypad. The programmed and commissioning is easily achieved by using keypad (show on the right) to scroll through the simple but effective menu options. The menu is password protected.
The lasers have a resolution of 0.01m and is accurate up to 0.1% of full scale. It also has two separate relays (each with a normally open and normally closed contact) of which the set and reset points can be adjusted according to the installation requirements.
The AL40/100 has been CE certified and can be supplied in different colours (shown below):
